EtymologyThe word book comes from , which in turn comes from the root , to ' '. In like , , —'letter' is cognate with 'beech'. In Russian, and Macedonian, the word () or () refers to a primary school textbook that helps young children master the techniques of reading and writing. It is thus conjectured that the earliest writings may have been carved on beech wood. The Latin word , meaning a book in the modern sense (bound and with separate leaves), originally meant 'block of wood'.
AntiquityWhen were created in s, a variety of objects, such as stone, , tree bark, metal sheets, and bones, were used for writing; these are studied in .
TabletA tablet is a physically robust writing medium, suitable for casual transport and writing. s were flattened and mostly dry pieces of clay that could be easily carried, and impressed with a . They were used as a writing medium, especially for writing in , throughout the and well into the . s were pieces of wood covered in a coating of wax thick enough to record the impressions of a stylus. They were the normal writing material in schools, in accounting, and for taking notes. They had the advantage of being reusable: the wax could be melted, and reformed into a blank. The custom of binding several wax tablets together (Roman ''pugillares'') is a possible precursor of modern bound (codex) books. The etymology of the word ''codex'' (block of wood) also suggests that it may have developed from wooden wax tablets.
ScrollScrolls can be made from , a thick material made by weaving the stems of the papyrus plant, then pounding the woven sheet with a hammer-like tool until it is flattened. Papyrus was used for writing in , perhaps as early as the First Dynasty, although the first evidence is from the account books of King of the (about 2400 BC). Papyrus sheets were glued together to form a . Tree bark such as and other materials were also used. According to (History 5:58), the brought writing and papyrus to Greece around the 10th or 9th century BC. The Greek word for papyrus as writing material (''biblion'') and book (''biblos'') come from the Phoenician port town , through which papyrus was exported to Greece. From Greek we also derive the word tome ( el, τόμος), which originally meant a slice or piece and from there began to denote "a roll of papyrus". ''Tomus'' was used by the Latins with exactly the same meaning as ''volumen'' (see also below the explanation by Isidore of Seville). Whether made from papyrus, , or paper, scrolls were the dominant form of book in the Hellenistic, Roman, Chinese, Hebrew, and Macedonian cultures. The more modern book format form took over the Roman world by , but the scroll format persisted much longer in Asia.
Codex(d. 636) explained the then-current relation between codex, book and scroll in his '' '' (VI.13): "A codex is composed of many books; a book is of one scroll. It is called codex by way of metaphor from the trunks (''codex'') of trees or vines, as if it were a wooden stock, because it contains in itself a multitude of books, as it were of branches." Modern usage differs. A codex (in modern usage) is the first information repository that modern people would recognize as a "book": leaves of uniform size in some manner along one edge, and typically held between two made of some more robust material. The first written mention of the codex as a form of book is from , in his ''Apophoreta'' CLXXXIV at the end of the first century, where he praises its compactness. However, the codex never gained much popularity in the pagan Hellenistic world, and only within the Christian community did it gain widespread use. This change happened gradually during the 3rd and 4th centuries, and the reasons for adopting the codex form of the book are several: the format is more economical, as both sides of the writing material can be used; and it is portable, searchable, and easy to conceal. A book is much easier to read, to find a page that you want, and to flip through. A scroll is more awkward to use. The Christian s may also have wanted to distinguish their writings from the pagan and Judaic texts written on scrolls. In addition, some metal books were made, that required smaller pages of metal, instead of an impossibly long, unbending scroll of metal. A book can also be easily stored in more compact places, or side by side in a tight library or shelf space.
ManuscriptsThe fall of the in the 5th century AD saw the decline of the . Papyrus became difficult to obtain due to lack of contact with Egypt, and parchment, which had been used for centuries, became the main writing material. Parchment is a material made from processed animal skin and used—mainly in the past—for writing on. Parchment is most commonly made of calfskin, sheepskin, or goatskin. It was historically used for writing documents, notes, or the pages of a book. Parchment is limed, scraped and dried under tension. It is not tanned, and is thus different from leather. This makes it more suitable for writing on, but leaves it very reactive to changes in relative humidity and makes it revert to rawhide if overly wet. Monasteries carried on the writing tradition in the . , in the monastery of Vivarium (established around 540), stressed the importance of copying texts. , in his '' '' (completed around the middle of the 6th century) later also promoted reading. The ''Rule of Saint Benedict'' (Ch. XLVIII), which set aside certain times for reading, greatly influenced the monastic culture of the and is one of the reasons why the clergy were the predominant readers of books. The tradition and style of the Roman Empire still dominated, but slowly the peculiar medieval book culture emerged. Before the invention and adoption of the , almost all books were copied by hand, which made books expensive and comparatively rare. Smaller monasteries usually had only a few dozen books, medium-sized perhaps a few hundred. By the 9th century, larger collections held around 500 volumes and even at the end of the Middle Ages, the papal library in and Paris library of the held only around 2,000 volumes. The '' '' of the monastery was usually located over the . Artificial light was forbidden for fear it may damage the manuscripts. There were five types of scribes: * Calligraphers, who dealt in fine book production * Copyists, who dealt with basic production and correspondence * Correctors, who collated and compared a finished book with the manuscript from which it had been produced * Illuminators, who painted illustrations * Rubricators, who painted in the red letters The bookmaking process was long and laborious. The parchment had to be prepared, then the unbound pages were planned and ruled with a blunt tool or lead, after which the text was written by the , who usually left blank areas for illustration and . Finally, the book was bound by the . Different types of ink were known in antiquity, usually prepared from soot and gum, and later also from nuts and iron vitriol. This gave writing a brownish black color, but black or brown were not the only colors used. There are texts written in red or even gold, and different colors were used for illumination. For very luxurious manuscripts the whole parchment was colored purple, and the text was written on it with gold or silver (for example, ). Irish monks introduced spacing between words in the 7th century. This facilitated reading, as these monks tended to be less familiar with Latin. However, the use of spaces between words did not become commonplace before the 12th century. It has been argued that the use of spacing between words shows the transition from semi-vocalized reading into silent reading. The first books used or ( ) for the pages. The book covers were made of wood and covered with leather. Because dried parchment tends to assume the form it had before processing, the books were fitted with clasps or straps. During the later , when public libraries appeared, up to the 18th century, books were often chained to a bookshelf or a to prevent theft. These chained books are called ''libri catenati''. At first, books were copied mostly in monasteries, one at a time. With the rise of universities in the 13th century, the of the time led to an increase in the demand for books, and a new system for copying books appeared. The books were divided into unbound leaves (''pecia''), which were lent out to different copyists, so the speed of book production was considerably increased. The system was maintained by secular stationers guilds, which produced both religious and non-religious material. has kept the art of the scribe alive up to the present. According to Jewish tradition, the scroll placed in a must be written by hand on parchment and a printed book would not do, though the congregation may use printed prayer books and printed copies of the Scriptures are used for study outside the . A "scribe" is a highly respected member of any observant Jewish community.
Middle EastPeople of various religious (Jews, Christians, Zoroastrians, Muslims) and ethnic backgrounds (Syriac, Coptic, Persian, Arab etc.) in the Middle East also produced and bound books in the (mid 8th century to 1258), developing advanced techniques in , and bookbinding. A number of cities in the medieval Islamic world had book production centers and book markets. Yaqubi (d. 897) says that in his time Baghdad had over a hundred booksellers. Book shops were often situated around the town's principal mosque as in , , that has a street named ''Kutubiyyin'' or book sellers in English and the famous is named so because of its location in this street. The medieval also used a method of reproducing reliable copies of a book in large quantities known as check reading, in contrast to the traditional method of a single scribe producing only a single copy of a single manuscript. In the check reading method, only "authors could authorize copies, and this was done in public sessions in which the copyist read the copy aloud in the presence of the author, who then certified it as accurate." With this check-reading system, "an author might produce a dozen or more copies from a single reading," and with two or more readings, "more than one hundred copies of a single book could easily be produced." By using as writing material the relatively cheap paper instead of parchment or papyrus the Muslims, in the words of Pedersen "accomplished a feat of crucial significance not only to the history of the Islamic book, but also to the whole world of books".
Wood block printingIn , a relief image of an entire page was carved into blocks of wood, inked, and used to print copies of that page. This method originated in China, in the (before 220 AD), as a method of on and later , and was widely used throughout . The oldest dated book printed by this method is '' '' (868 AD). The method (called when used in art) arrived in Europe in the early 14th century. Books (known as block-books), as well as playing-cards and religious pictures, began to be produced by this method. Creating an entire book was a painstaking process, requiring a hand-carved block for each page; and the wood blocks tended to crack, if stored for long. The monks or people who wrote them were paid highly.
Movable type and incunabulaThe Chinese inventor made of earthenware c. 1045, but there are no known surviving examples of his printing. Around 1450, in what is commonly regarded as an independent invention, invented movable type in Europe, along with innovations in casting the type based on a matrix and . This invention gradually made books less expensive to produce, and more widely available. Early printed books, single sheets and images which were created before 1501 in Europe are known as s or ''incunabula''. "A man born in 1453, the year of the fall of Constantinople, could look back from his fiftieth year on a lifetime in which about eight million books had been printed, more perhaps than all the scribes of Europe had produced since Constantine founded his city in AD 330."
19th century to 21st centuriesSteam-powered printing presses became popular in the early 19th century. These machines could print 1,100 sheets per hour, but workers could only set 2,000 letters per hour. and typesetting machines were introduced in the late 19th century. They could set more than 6,000 letters per hour and an entire line of type at once. There have been numerous improvements in the printing press. As well, the conditions for have been improved through the gradual relaxation of restrictive censorship laws. See also , , . In mid-20th century, European book production had risen to over 200,000 titles per year. Throughout the 20th century, libraries have faced an ever-increasing rate of publishing, sometimes called an . The advent of and the means that much new information is not printed in paper books, but is made available online through a , on , in the form of e-books or other online media. An on-line book is an e-book that is available online through the internet. Though many books are produced digitally, most digital versions are not available to the public, and there is no decline in the rate of paper publishing. There is an effort, however, to convert books that are in the into a digital medium for unlimited redistribution and infinite availability. This effort is spearheaded by combined with . There have also been new developments in the process of publishing books. Technologies such as POD or " ", which make it possible to print as few as one book at a time, have made self-publishing (and vanity publishing) much easier and more affordable. On-demand publishing has allowed publishers, by avoiding the high costs of warehousing, to keep low-selling books in print rather than declaring them out of print.
Indian manuscriptsGoddess image dated 132 AD excavated from depicts her holding a manuscript in her left hand represented as a bound and tied or birch bark manuscript. In India a bounded manuscript made of birch bark or palm leaf existed side by side since antiquity. The text in palm leaf manuscripts was inscribed with a knife pen on rectangular cut and cured palm leaf sheets; colourings were then applied to the surface and wiped off, leaving the ink in the incised grooves. Each sheet typically had a hole through which a string could pass, and with these the sheets were tied together with a string to bind like a book.
Mesoamerican CodexThe codices of pre-Columbian (Mexico and Central America) had the same form as the European codex, but were instead made with long folded strips of either fig bark ( ) or plant fibers, often with a layer of applied before writing. codices were written as late as the 16th century (see and ). Those written before the Spanish conquests seem all to have been single long sheets folded -style, sometimes written on both sides of the local '' '' paper.
Modern manufacturingThe methods used for the printing and binding of books continued fundamentally unchanged from the 15th century into the early 20th century. While there was more , a in 1900 had much in common with Johannes Gutenberg, Gutenberg. Printing press, Gutenberg's invention was the use of movable metal types, assembled into words, lines, and pages and then printed by letterpress to create multiple copies. Modern paper books are printed on Printing and writing paper, papers designed specifically for printed books. Traditionally, book papers are off-white or low-white papers (easier to read), are opaque to minimise the show-through of text from one side of the page to the other and are (usually) made to tighter caliper or thickness specifications, particularly for case-bound books. Different paper qualities are used depending on the type of book: Machine finished coated papers, woodfree uncoated papers, coated fine papers and special fine papers are common paper grades. Today, the majority of books are printed by offset lithography. When a book is printed, the pages are laid out on the plate so that after the printed sheet is folded the pages will be in the correct sequence. Books tend to be manufactured nowadays in a few standard sizes. The Book size, sizes of books are usually specified as "trim size": the size of the page after the sheet has been folded and trimmed. The standard sizes result from sheet sizes (therefore machine sizes) which became popular 200 or 300 years ago, and have come to dominate the industry. British conventions in this regard prevail throughout the English-speaking world, except for the USA. The European book manufacturing industry works to a completely different set of standards.
LayoutModern bound books are organized according to a particular format called the book's ''layout''. Although there is great variation in layout, modern books tend to adhere to as set of rules with regard to what the parts of the layout are and what their content usually includes. A basic layout will include a ''front cover'', a ''back cover'' and the book's content which is called its ''body copy'' or ''content pages''. The front cover often bears the book's title (and subtitle, if any) and the name of its author or editor(s). The ''inside front cover'' page is usually left blank in both hardcover and paperback books. The next section, if present, is the book's ''front matter'', which includes all textual material after the front cover but not part of the book's content such as a foreword, a dedication, a table of contents and publisher data such as the book's edition or printing number and place of publication. Between the body copy and the back cover goes the ''end matter'' which would include any indices, sets of tables, diagrams, glossaries or lists of cited works (though an edited book with several authors usually places cited works at the end of each authored chapter). The ''inside back cover'' page, like that inside the front cover, is usually blank. The ''back cover'' is the usual place for the book's ISBN and maybe a photograph of the author(s)/ editor(s), perhaps with a short introduction to them. Also here often appear plot summaries, barcodes and excerpted reviews of the book.
PrintingSome books, particularly those with shorter runs (i.e. fewer copies) will be printed on sheet-fed offset presses, but most books are now printed on web presses, which are fed by a continuous roll of paper, and can consequently print more copies in a shorter time. As the production line circulates, a complete "book" is collected together in one stack, next to another, and another web press carries out the folding itself, delivering bundles of ''signatures'' (sections) ready to go into the gathering line. Note that the pages of a book are printed two at a time, not as one complete book. Excess numbers are printed to make up for any spoilage due to make-readies or test pages to assure final print quality. A ''make-ready'' is the preparatory work carried out by the pressmen to get the printing press up to the required quality of Impression (publishing), impression. Included in make-ready is the time taken to mount the plate onto the machine, clean up any mess from the previous job, and get the press up to speed. As soon as the pressman decides that the printing is correct, all the make-ready sheets will be discarded, and the press will start making books. Similar make readies take place in the folding and binding areas, each involving spoilage of paper.
BindingAfter the signatures are folded and gathered, they move into the bindery. In the middle of last century there were still many trade binders – stand-alone binding companies which did no printing, specializing in binding alone. At that time, because of the dominance of letterpress printing, typesetting and printing took place in one location, and binding in a different factory. When type was all metal, a typical book's worth of type would be bulky, fragile and heavy. The less it was moved in this condition the better: so printing would be carried out in the same location as the typesetting. Printed sheets on the other hand could easily be moved. Now, because of increasing Automation, computerization of preparing a book for the printer, the typesetting part of the job has flowed upstream, where it is done either by separately contracting companies working for the publisher, by the publishers themselves, or even by the authors. Mergers in the book manufacturing industry mean that it is now unusual to find a bindery which is not also involved in book printing (and vice versa). If the book is a hardcover, hardback its path through the bindery will involve more points of activity than if it is a paperback. Unsewn binding, is now increasingly common. The signatures of a book can also be held together by "Smyth sewing" using needles, "McCain sewing", using drilled holes often used in schoolbook binding, or "notch binding", where gashes about an inch long are made at intervals through the fold in the spine of each signature. The rest of the binding process is similar in all instances. Sewn and notch bound books can be bound as either hardbacks or paperbacks.
Finishing"Making cases" happens off-line and prior to the book's arrival at the binding line. In the most basic case-making, two pieces of cardboard are placed onto a glued piece of cloth with a space between them into which is glued a thinner board cut to the width of the spine of the book. The overlapping edges of the cloth (about 5/8" all round) are folded over the boards, and pressed down to adhere. After case-making the stack of cases will go to the foil stamping area for adding decorations and type.
Digital printingRecent developments in book manufacturing include the development of digital printing. Book pages are printed, in much the same way as an office copier works, using toner rather than ink. Each book is printed in one pass, not as separate signatures. Digital printing has permitted the manufacture of much smaller quantities than offset, in part because of the absence of make readies and of spoilage. One might think of a web press as printing quantities over 2000, quantities from 250 to 2000 being printed on sheet-fed presses, and digital presses doing quantities below 250. These numbers are of course only approximate and will vary from supplier to supplier, and from book to book depending on its characteristics. Digital printing has opened up the possibility of print-on-demand, where no books are printed until after an order is received from a customer.
E-bookIn the 2000s, due to the rise in availability of affordable handheld computing devices, the opportunity to share texts through electronic means became an appealing option for media publishers. Thus, the "e-book" was made. The term e-book is a contraction of "electronic book"; it refers to a book-length publication in digital form. An e-book is usually made available through the internet, but also on CD-ROM and other forms. E-Books may be read either via a computing device with an LED display such as a traditional computer, a smartphone or a tablet computer; or by means of a portable e-ink display device known as an e-book reader, such as the Sony Reader, Barnes & Noble Nook, Kobo eReader, or the Amazon Kindle. E-book readers attempt to mimic the experience of reading a print book by using this technology, since the displays on e-book readers are much less reflective.
DesignBook design is the art of incorporating the content, style, format, design, and sequence of the various components of a book into a coherent whole. In the words of Jan Tschichold, book design "though largely forgotten today, methods and rules upon which it is impossible to improve have been developed over centuries. To produce perfect books these rules have to be brought back to life and applied." Richard Hendel describes book design as "an arcane subject" and refers to the need for a context to understand what that means. Many different creators can contribute to book design, including graphic designers, artists and editors.
SizesThe size of a modern book is based on the printing area of a common flatbed press. The pages of type were arranged and clamped in a frame, so that when printed on a sheet of paper the full size of the press, the pages would be right side up and in order when the sheet was folded, and the folded edges trimmed. The most common book sizes are: * Quarto (4to): the sheet of paper is folded twice, forming four leaves (eight pages) approximately 11–13 inches (c. 30 cm) tall * Octavo (8vo): the most common size for current hardcover books. The sheet is folded three times into eight leaves (16 pages) up to inches (c. 23 cm) tall. * DuoDecimo (12mo): a size between 8vo and 16mo, up to inches (c. 18 cm) tall * Sextodecimo (16mo): the sheet is folded four times, forming 16 leaves (32 pages) up to inches (c. 15 cm) tall Sizes smaller than 16mo are: * 24mo: up to inches (c. 13 cm) tall. * 32mo: up to 5 inches (c. 12 cm) tall. * 48mo: up to 4 inches (c. 10 cm) tall. * 64mo: up to 3 inches (c. 8 cm) tall. Small books can be called ''booklets''. Sizes larger than quarto are: * Folio: up to 15 inches (c. 38 cm) tall. * Elephant Folio: up to 23 inches (c. 58 cm) tall. * Atlas Folio: up to 25 inches (c. 63 cm) tall. * Double Elephant Folio: up to 50 inches (c. 127 cm) tall. The largest extant medieval manuscript in the world is Codex Gigas 92 × 50 × 22 cm. The world's largest book is made of stone and is in Kuthodaw Pagoda (Burma).
By contentA common separation by content are fiction and non-fiction books. This simple separation can be found in most collection (museum), collections, library, libraries, and bookstores. There are other types such as books of sheet music.
FictionMany of the books published today are "fiction", meaning that they contain invented material, and are creative literature. Other literary forms such as poetry are included in the broad category. Most fiction is additionally categorized by literary form and genre. The novel is the most common form of fiction book. Novels are stories that typically feature a plot (narrative), plot, setting (fiction), setting, theme (literature), themes and character (arts), characters. Stories and narrative are not restricted to any topic; a novel can be whimsical, serious or controversy, controversial. The novel has had a tremendous impact on entertainment and publishing Market (economics), markets. A novella is a term sometimes used for fiction prose typically between 17,500 and 40,000 words, and a Novella, novelette between 7,500 and 17,500. A short story may be any length up to 10,000 words, but these word lengths vary. Comic books or graphic novels are books in which the story is illustrated. The characters and narrators use speech or thought bubbles to express verbal language.
Non-fictionNon-fiction books are in principle based on fact, on subjects such as history, politics, social and cultural issues, as well as autobiographies and memoirs. Nearly all academic literature is non-fiction. A reference book is a general type of non-fiction book which provides information as opposed to telling a story, essay, commentary, or otherwise supporting a point of view. An almanac is a very general reference book, usually one-volume, with lists of data and information on many topics. An encyclopedia is a book or set of books designed to have more in-depth articles on many topics. A book listing words, their etymology, meanings, and other information is called a dictionary. A book which is a collection of maps is an atlas. A more specific reference book with tables or lists of data and information about a certain topic, often intended for professional use, is often called a handbook. Books which try to list references and abstracts in a certain broad area may be called an index (publishing), index, such as ''Engineering Index'', or abstract (summary), abstracts such as chemical abstracts and biological abstracts. Books with technical information on how to do something or how to use some equipment are called instruction manuals. Other popular how-to books include cookbooks and home improvement books. Students typically store and carry textbooks and schoolbooks for study purposes.
Non-published booksMany types of book are private, often filled in by the owner, for a variety of personal records. Elementary school pupils often use workbooks, which are published with spaces or blanks to be filled by them for study or homework. In US higher education, it is common for a student to take an exam using a blue book exam, blue book. There is a large set of books that are made only to write private ideas, notes, and accounts. These books are rarely published and are typically destroyed or remain private. Notebooks are blank papers to be written in by the user. Students and writers commonly use them for taking notes. Scientists and other researchers use lab notebooks to record their notes. They often feature spiral coil bindings at the edge so that pages may easily be torn out. Address books, phone books, and meeting, calendar/appointment books are commonly used on a daily basis for recording appointments, meetings and personal Address (geography), contact information. Books for recording periodic entries by the user, such as daily information about a journey, are called logbooks or simply logs. A similar book for writing the owner's daily private personal events, information, and ideas is called a diary or personal journal. Businesses use accounting books such as journals and ledgers to record financial data in a practice called bookkeeping (now usually held on computers rather than in hand-written form).
Other typesThere are several other types of books which are not commonly found under this system. photograph album, Albums are books for holding a group of items belonging to a particular theme, such as a set of photographs, card collections, and memorabilia. One common example is stamp albums, which are used by many hobbyists to protect and organize their collections of postage stamps. Such albums are often made using removable plastic pages held inside in a ringed binder or other similar holder. Picture books are books for children with pictures on every page and less text (or even no text). Hymnals are books with collections of musical hymns that can typically be found in church (building), churches. Breviary, Prayerbooks or missals are books that contain written prayers and are commonly carried by monks, nuns, and other devoted followers or clergy. Lap books are a learning tool created by students.
Decodable readers and leveled booksA leveled book collection is a set of books organized in levels of difficulty from the easy books appropriate for an emergent reader to longer more complex books adequate for advanced readers. Decodable readers or books are a specialized type of leveled books that use decodable text only including controlled lists of words, sentences and stories consistent with the letters and phonics that have been taught to the emergent reader. New sounds and letters are added to higher level decodable books, as the level of instruction progresses, allowing for higher levels of accuracy, comprehension and fluency.
By physical formatHardcover books have a stiff binding. Paperback books have cheaper, flexible covers which tend to be less durable. An alternative to paperback is the glossy cover, otherwise known as a dust cover, found on magazines, and comic books. Spiral-bound books are bound by spirals made of metal or plastic. Examples of spiral-bound books include teachers' manuals and puzzle books (crosswords, sudoku). Publishing is a process for producing pre-printed books, magazines, and newspapers for the reader/user to buy. Publishers may produce low-cost, pre-publication copies known as galley proof, galleys or 'bound proofs' for promotional purposes, such as generating reviews in advance of publication. Galleys are usually made as cheaply as possible, since they are not intended for sale.
LibrariesPrivate or personal libraries made up of non-fiction and fiction books, (as opposed to the state or institutional records kept in archives) first appeared in classical Greece. In the ancient world, the maintaining of a library was usually (but not exclusively) the privilege of a wealthy individual. These libraries could have been either private or public, i.e. for people who were interested in using them. The difference from a modern public library lies in the fact that they were usually not funded from public sources. It is estimated that in the city of Rome at the end of the 3rd century there were around 30 public libraries. Public libraries also existed in other cities of the ancient History of the Mediterranean region, Mediterranean region (for example, Library of Alexandria). Later, in the Middle Ages, monasteries and universities had also libraries that could be accessible to general public. Typically not the whole collection was available to public, the books could not be borrowed and often were chained to reading stands to prevent theft. The beginning of modern public library begins around 15th century when individuals started to donate books to towns. The growth of a public library system in the United States started in the late 19th century and was much helped by donations from Andrew Carnegie. This reflected classes in a society: The poor or the middle class had to access most books through a public library or by other means while the rich could afford to have a private library built in their homes. In the United States the Boston Public Library 1852 ''Report of the Trustees'' established the justification for the public library as a tax-supported institution intended to extend educational opportunity and provide for general culture. The advent of paperback books in the 20th century led to an explosion of popular publishing. Paperback books made owning books affordable for many people. Paperback books often included works from genres that had previously been published mostly in pulp magazines. As a result of the low cost of such books and the spread of bookstores filled with them (in addition to the creation of a smaller market of extremely cheap used paperbacks) owning a private library ceased to be a status symbol for the rich. In library and booksellers' catalogues, it is common to include an abbreviation such as "Crown 8vo" to indicate the paper size from which the book is made. When rows of books are lined on a book holder, bookends are sometimes needed to keep them from slanting.
Identification and classificationDuring the 20th century, librarians were concerned about keeping track of the many books being added yearly to the Gutenberg Galaxy. Through a global society called the International Federation of Library Associations and Institutions (IFLA), they devised a series of tools including the International Standard Bibliographic Description (ISBD). Each book is specified by an International Standard Book Number, or ISBN, which is unique to every edition of every book produced by participating publishers, worldwide. It is managed by the ISBN Society. An ISBN has four parts: the first part is the country code, the second the publisher code, and the third the title code. The last part is a check digit, and can take values from 0–9 and X (10). The European Article Number, EAN Barcodes numbers for books are derived from the ISBN by prefixing 978, for Bookland, and calculating a new check digit. Commercial publishers in industrialized countries generally assign ISBNs to their books, so buyers may presume that the ISBN is part of a total international system, with no exceptions. However, many government publishers, in industrial as well as developing countries, do not participate fully in the ISBN system, and publish books which do not have ISBNs. A large or public collection requires a Library catalog, catalogue. Codes called "call numbers" relate the books to the catalogue, and determine their locations on the shelves. Call numbers are based on a Library classification system. The call number is placed on the spine of the book, normally a short distance before the bottom, and inside. Institutional or national standards, such as American National Standards Institute, ANSI/NISO Z39.41 - 1997, establish the correct way to place information (such as the title (publishing), title, or the name of the author) on book spines, and on "shelvable" book-like objects, such as containers for DVDs, video tapes and software. One of the earliest and most widely known systems of cataloguing books is the Dewey Decimal Classification, Dewey Decimal System. Another widely known system is the Library of Congress Classification system. Both systems are biased towards subjects which were well represented in US libraries when they were developed, and hence have problems handling new subjects, such as computing, or subjects relating to other cultures. Information about books and authors can be stored in databases like online general-interest book databases. Metadata, which means "data about data" is information about a book. Metadata about a book may include its title, ISBN or other classification number (see above), the names of contributors (author, editor, illustrator) and publisher, its date and size, the language of the text, its subject matter, etc.

UsesAside from the primary purpose of reading them, books are also used for other ends: * A book can be an artistic artifact, a piece of art; this is sometimes known as an artists' book. * A book may be evaluated by a reader or professional writer to create a book review. * A book may be read by a group of people to use as a spark for social or academic discussion, as in a book discussion club, book club. * A book may be studied by students as the subject of a writing and analysis exercise in the form of a book report. * Books are sometimes used for their exterior appearance to decorative arts, decorate a room, such as a study (room), study.
Book marketingOnce the book is published, it is put on the market by the distributors and the bookstores. Meanwhile, his promotion comes from various media reports. Book marketing is governed by the law in many states.
Other forms of secondary spreadIn recent years, the book had a second life in the form of reading aloud. This is called public readings of published works, with the assistance of professional readers (often known actors) and in close collaboration with writers, publishers, booksellers, librarians, leaders of the literary world and artists. Many individual or collective practices exist to increase the number of readers of a book. Among them: * abandonment of books in public places, coupled or not with the use of the Internet, known as the bookcrossing; * provision of free books in third places like bars or cafes; * itinerant or temporary libraries; * free public libraries in the area.
Evolution of the book industryThis form of the book chain has hardly changed since the eighteenth century, and has not always been this way. Thus, the author has asserted gradually with time, and the copyright dates only from the nineteenth century. For many centuries, especially before the invention of printing, each freely copied out books that passed through his hands, adding if necessary his own comments. Similarly, bookseller and publisher jobs have emerged with the invention of printing, which made the book an industrial product, requiring structures of production and marketing. The invention of the Internet, e-readers, tablets, and projects like Wikipedia and Gutenberg, are likely to strongly change the book industry in the years to come.
Paper and conservationPaper was first made in China as early as 200 BC, and reached Europe through History of Islam, Muslim territories. At first made of rags, the industrial revolution changed paper-making practices, allowing for paper to be made out of wood pulp. Papermaking in Europe began in the 11th century, although was also common there as page material up until the beginning of the 16th century, vellum being the more expensive and durable option. Printers or publishers would often issue the same publication on both materials, to cater to more than one market. Paper made from wood pulp became popular in the early 20th century, because it was cheaper than linen or abaca cloth-based papers. Pulp-based paper made books less expensive to the general public. This paved the way for huge leaps in the rate of literacy in industrialised nations, and enabled the spread of information during the Second Industrial Revolution. Pulp paper, however, contains acid which eventually destroys the paper from within. Earlier techniques for making paper used limestone rollers, which neutralized the acid in the pulp. Books printed between 1850 and 1950 are primarily at risk; more recent books are often printed on acid-free or alkaline paper. Libraries today have to consider mass deacidification of their older collections in order to prevent decay. Stability of the climate is critical to the long-term preservation of paper and book material. Good air circulation is important to keep fluctuation in climate stable. The HVAC system should be up to date and functioning efficiently. Light is detrimental to collections. Therefore, care should be given to the collections by implementing light control. General housekeeping issues can be addressed, including pest control. In addition to these helpful solutions, a library must also make an effort to be prepared if a disaster occurs, one that they cannot control. Time and effort should be given to create a concise and effective disaster plan to counteract any damage incurred through "acts of God", therefore an emergency management plan should be in place.
