Encyclopedias have existed for around 2,000 years and have evolved considerably during that time as regards language (written in a major international or a vernacular language), size (few or many volumes), intent (presentation of a global or a limited range of knowledge), cultural perspective (authoritative, ideological, didactic, utilitarian), authorship (qualifications, style), readership (education level, background, interests, capabilities), and the technologies available for their production and distribution (hand-written manuscripts, small or large print runs, Internet). As a valued source of reliable information compiled by experts, printed versions found a prominent place in libraries, schools and other educational institutions.
The appearance of
digital and open-source versions in the 21st century, such as
Wikipedia, has vastly expanded the accessibility, authorship, readership, and variety of encyclopedia entries.
Etymology
The word ''
encyclopedia
An encyclopedia (American English) or encyclopædia (British English) is a reference work or compendium providing summaries of knowledge either general or special to a particular field or discipline. Encyclopedias are divided into articles ...
'' (''encyclo'', ''pedia'') comes from the
Koine Greek ,
transliterated , meaning 'general education' from (), meaning 'circular, recurrent, required regularly, general' and (), meaning 'education, rearing of a child'; together, the phrase literally translates as 'complete instruction' or 'complete knowledge'. However, the two separate words were reduced to a single word due to a scribal error by copyists of a
Latin manuscript edition of
Quintillian in 1470. The copyists took this phrase to be a single Greek word, ''enkyklopaedia'', with the same meaning, and this spurious Greek word became the
New Latin word ''encyclopaedia'', which in turn came into English. Because of this compounded word, fifteenth-century readers and since have often, and incorrectly, thought that the Roman authors
Quintillian and
Pliny described an ancient genre.
Characteristics
The modern encyclopedia was developed from the
dictionary
A dictionary is a listing of lexemes from the lexicon of one or more specific languages, often arranged alphabetically (or by radical and stroke for ideographic languages), which may include information on definitions, usage, etymologies ...
in the 18th century. Historically, both encyclopedias and dictionaries have been researched and written by well-educated, well-informed content

s, but they are significantly different in structure. A dictionary is a linguistic work which primarily focuses on alphabetical listing of
words and their
definitions.
Synonym
A synonym is a word, morpheme, or phrase that means exactly or nearly the same as another word, morpheme, or phrase in a given language. For example, in the English language, the words ''begin'', ''start'', ''commence'', and ''initiate'' are all ...
ous words and those related by the subject matter are to be found scattered around the dictionary, giving no obvious place for in-depth treatment. Thus, a dictionary typically provides limited
information,
analysis or background for the word defined. While it may offer a definition, it may leave the reader lacking in
understanding the meaning, significance or limitations of a
term, and how the term relates to a broader field of knowledge.
To address those needs, an encyclopedia article is typically not limited to simple definitions, and is not limited to defining an individual word, but provides a more extensive meaning for a ''subject or

. An encyclopedia is, theoretically, not written in order to convince, although one of its goals is indeed to convince its reader of its own veracity.
Four major elements
There are four major elements that define an encyclopedia: its subject matter, its scope, its method of organization, and its method of production:
# Encyclopedias can be general, containing articles on topics in every field (the English-language ''
Encyclopædia Britannica'' and German ''
Brockhaus'' are well-known examples).
General encyclopedias may contain guides on how to do a variety of things, as well as embedded dictionaries and
gazetteers. There are also encyclopedias that cover a wide variety of topics from a particular cultural, ethnic, or national perspective, such as the ''
Great Soviet Encyclopedia'' or ''
Encyclopaedia Judaica''.
# Works of encyclopedic scope aim to convey the important accumulated knowledge for their subject domain, such as an encyclopedia of
medicine,
philosophy
Philosophy (from , ) is the systematized study of general and fundamental questions, such as those about existence, reason, knowledge, values, mind, and language. Such questions are often posed as problems to be studied or resolved. Some ...
or
law. Works vary in the breadth of material and the depth of discussion, depending on the
target audience.
# Some systematic method of organization is essential to making an encyclopedia usable for reference. There have historically been two main methods of organizing printed encyclopedias: the
alphabetical method (consisting of a number of separate articles, organized in alphabetical order) and organization by
hierarchical
A hierarchy (from Greek: , from , 'president of sacred rites') is an arrangement of items (objects, names, values, categories, etc.) that are represented as being "above", "below", or "at the same level as" one another. Hierarchy is an important ...
categories.
The former method is today the more common, especially for general works. The fluidity of
electronic media, however, allows new possibilities for multiple methods of organization of the same content. Further, electronic media offer new capabilities for search,
indexing and
cross reference. The
epigraph from
Horace

on the title page of the 18th century ''Encyclopédie'' suggests the importance of the structure of an encyclopedia: "What grace may be added to commonplace matters by the power of order and connection."
# As modern multimedia and the information age have evolved, new methods have emerged for the collection, verification, summation, and presentation of information of all kinds. Projects such as
Everything2,
Encarta,
h2g2, and
Wikipedia are examples of new forms of the encyclopedia as

becomes simpler. The method of production for an encyclopedia historically has been supported in both for-profit and non-profit contexts. The ''
Great Soviet Encyclopedia'' mentioned above was entirely state sponsored, while the ''Britannica'' was supported as a for-profit institution. By comparison, Wikipedia is supported by volunteers contributing in a non-profit environment under the organization of the
Wikimedia Foundation.
Encyclopedic dictionaries
Some works entitled "dictionaries" are actually similar to encyclopedias, especially those concerned with a particular field (such as the ''
Dictionary of the Middle Ages'', the ''
Dictionary of American Naval Fighting Ships'', and ''
Black's Law Dictionary
''Black's Law Dictionary'' is the most frequently used legal dictionary in the United States. Henry Campbell Black (1860–1927) was the author of the first two editions of the dictionary.

after its first edition in recognition of the use of proper nouns in common communication, and the words derived from such proper nouns.
Differences between encyclopedias and dictionaries
There are some broad differences between encyclopedias and dictionaries. Most noticeably, encyclopedia articles are longer, fuller and more thorough than entries in most general-purpose dictionaries.
There are differences in content as well. Generally speaking, dictionaries provide
linguistic information about words themselves, while encyclopedias focus more on the thing for which those words stand.
Thus, while dictionary entries are inextricably fixed to the word described, encyclopedia articles can be given a different entry name. As such, dictionary entries are not fully translatable into other languages, but encyclopedia articles can be.
In practice, however, the distinction is not concrete, as there is no clear-cut difference between factual, "encyclopedic" information and linguistic information such as appears in dictionaries.
Thus encyclopedias may contain material that is also found in dictionaries, and vice versa.
In particular, dictionary entries often contain factual information about the thing named by the word.
History
Encyclopedias have progressed from the beginning of history in written form, through medieval and modern times in print, and most recently, displayed on computer and distributed via computer networks, including the Internet.
Written encyclopedias
The earliest encyclopedic work to have survived to modern times is the ''
Naturalis Historia'' of
Pliny the Elder, a
Roman statesman living in the 1st century AD.
He compiled a work of 37 chapters covering
natural history, architecture, medicine,
geography, geology, and all aspects of the world around him.
This work became very popular in

Siribhoovalaya (Kannada: ಸಿರಿಭೂವಲಯ), dated between 800 A.D. to 15th century, is a work of
kannada literature written by
Kumudendu Muni, a Jain monk. It is unique because rather than employing alphabets, it is composed entirely in
Kannada numerals. Many philosophies which existed in the Jain classics are eloquently and skillfully interpreted in the work.
The enormous encyclopedic work in China of the ''
Four Great Books of Song'', compiled by the 11th century during the early
Song dynasty (960–1279), was a massive literary undertaking for the time. The last encyclopedia of the four, the ''
Prime Tortoise of the Record Bureau'', amounted to 9.4 million
Chinese characters in 1,000 written volumes.

Printed encyclopedias
Before the advent of the printing press, encyclopedic works were all hand copied and thus rarely available, beyond wealthy patrons or monastic men of learning: they were expensive, and usually written for those extending knowledge rather than those using it.
During the
Renaissance, the creation of
printing allowed a wider diffusion of encyclopedias and every scholar could have his or her own copy. The ''
De expetendis et fugiendis rebus'' by
Giorgio Valla was posthumously printed in 1501 by
Aldo Manuzio

), newly discovered and translated. The ''Margarita Philosophica'' by
Gregor Reisch, printed in 1503, was a complete encyclopedia explaining the
seven liberal arts.
Financial, commercial, legal, and intellectual factors changed the size of encyclopedias. Middle classes had more time to read and encyclopedias helped them to learn more. Publishers wanted to increase their output so some countries like Germany started selling books missing alphabetical sections, to publish faster. Also, publishers could not afford all the resources by themselves, so multiple publishers would come together with their resources to create better encyclopedias. Later, rivalry grew, causing copyright to occur due to weak underdeveloped laws.
John Harris is often credited with introducing the now-familiar alphabetic format in 1704 with his English ''Lexicon Technicum: Or, A Universal English Dictionary of Arts and Sciences: Explaining not only the Terms of Art, but the Arts Themselves'' – to give its full title. Organized alphabetically, its content does indeed contain explanation not merely of the terms used in the arts and sciences, but of the arts and sciences themselves.
Sir Isaac Newton contributed his only published work on chemistry to the second volume of 1710.
Encyclopédie
Encyclopædia Britannica
The ''
Encyclopædia Britannica'', had a modest beginning in Scotland: the first edition, issued between 1768 and 1771, had just three hastily completed volumes – A–B, C–L, and M–Z – with a total of 2,391 pages. By 1797, when the third edition was completed, it had been expanded to 18 volumes addressing a full range of topics, with articles contributed by a range of authorities on their subjects.
The ''Encyclopædia Britannica'' appeared in various editions throughout the nineteenth century, and the growth of
popular education and the
Mechanics' Institutes, spearheaded by the
Society for the Diffusion of Useful Knowledge led to the production of the ''
Penny Cyclopaedia'', as its title suggests issued in weekly numbers at a penny each like a newspaper.
In the early 20th century, the ''Encyclopædia Britannica'' reached its eleventh edition, and inexpensive encyclopedias such as ''
Harmsworth's Universal Encyclopaedia'' and ''
Everyman's Encyclopaedia'' were common.
Brockhaus
The German-language ''
Conversations-Lexikon'' was published at
Leipzig from 1796 to 1808, in 6 volumes. Paralleling other 18th century encyclopedias, its scope was expanded beyond that of earlier publications, in an effort at comprehensiveness. It was, however, intended not for scholarly use but to provide results of research and discovery in a simple and popular form without extensive detail. This format, a contrast to the ''Encyclopædia Britannica'', was widely imitated by later 19th century encyclopedias in Britain, the United States, France, Spain, Italy and other countries. Of the influential late-18th century and early-19th century encyclopedias, the ''Conversations-Lexikon'' is perhaps most similar in form to today's encyclopedias.
E.s in the US
In the United States, the 1950s and 1960s saw the introduction of several large popular encyclopedias, often sold on installment plans. The best known of these were ''
World Book'' and ''
Funk and Wagnalls''. As many as 90% were sold
door to door.
Jack Lynch says in his book ''You Could Look It Up'' that encyclopedia salespeople were so common that they became the butt of jokes. He describes their sales pitch saying, "They were selling not books but a lifestyle, a future, a promise of social mobility." A 1961 ''World Book'' ad said, "You are holding your family's future in your hands right now," while showing a feminine hand holding an order form.
Digital encyclopedias
By the late 20th century, encyclopedias were being published on
CD-ROM

s for use with personal computers.
Microsoft's ''
Encarta'', launched in 1993, was a landmark example as it had no printed equivalent. Articles were supplemented with video and audio files as well as numerous high-quality images. After sixteen years, Microsoft discontinued the Encarta line of products in 2009.
Digital encyclopedias enable "Encyclopedia Services" (e.g.
Wikimedia Enterprise) to facilitate programatic access to the content.
Free encyclopedias
The concept of a free encyclopedia began with the
Interpedia proposal on
Usenet in 1993, which outlined an Internet-based
online encyclopedia to which anyone could submit content and that would be freely accessible. Early projects in this vein included
Everything2 and
Open Site. In 1999,
Richard Stallman proposed the
GNUPedia, an online encyclopedia which, similar to the
GNU operating system, would be a "generic" resource. The concept was very similar to Interpedia, but more in line with Stallman's
GNU philosophy.
It was not until
Nupedia and later
Wikipedia that a stable free encyclopedia project was able to be established on the Internet.
The
English Wikipedia, which was started in 2001, became the world's largest encyclopedia in 2004 at the 300,000 article stage. By late 2005, Wikipedia had produced over two million articles in more than 80 languages with content licensed under the
copyleft GNU Free Documentation License
The GNU Free Documentation License (GNU FDL or simply GFDL) is a copyleft license for free documentation, designed by the Free Software Foundation (FSF) for the GNU Project. It is similar to the GNU General Public License, giving readers the r ...
. As of August 2009, Wikipedia had over 3 million articles in English and well over 10 million combined in over 250 languages. Wikipedia currently has
articles in English.
Since 2003, other free encyclopedias like the Chinese-language
Baidu Baike and
Hudong, as well as English language encyclopedias such as
Citizendium and
Knol have appeared, the latter of which has been discontinued.
Online encyclopedias
In January 1995,
Project Gutenberg started to publish the
ASCII text of the ''
Encyclopædia Britannica'', 11th edition (1911), but disagreement about the method halted the work after the first volume.
For trademark reasons this has been published as the ''
Gutenberg Encyclopedia''.
Project Gutenberg later restarted work on digitising and proofreading this encyclopedia. Project Gutenberg has published volumes in alphabetic order the most recent publication is ''Volume 17 Slice 8: Matter–Mecklenburg'' published on 7 April 2013. The latest ''Britannica'' was digitized by its publishers, and sold first as a CD-ROM, and later as an online service.
In 2001, ASCII text of all 28 volumes was published on
''Encyclopædia Britannica'' Eleventh Edition by source; a copyright claim was added to the materials included. The website no longer exists, but the contents are available from the
Internet Archive.
Other digitization projects have made progress in other titles. One example is ''
Easton's Bible Dictionary (1897)'' digitized by the
Christian Classics Ethereal Library.
A successful digitization of an encyclopedia was the
Bartleby Project's online adaptation of the ''
Columbia Encyclopedia'', Sixth Edition, in early 2000 and is updated periodically.
Other websites provide online encyclopedias, some of which are also available on Wikisource, but which may be more complete than those on Wikisource, or maybe different editions (see

).
Another related branch of activity is the creation of new, free content on a volunteer basis. In 1991, the participants of the
Usenet newsgroup
started a project to produce a real version of ''
The Hitchhiker's Guide to the Galaxy'', a fictional encyclopedia used in the works of
Douglas Adams. It became known as Project Galactic Guide. Although it originally aimed to contain only real, factual articles, the policy was changed to allow and encourage semi-real and unreal articles as well. Project Galactic Guide contains over 1700 articles, but no new articles have been added since 2000; this is probably partly due to the founding of
h2g2, a more official project along similar lines.
The 1993
Interpedia proposal was planned as an encyclopedia on the Internet to which everyone could contribute materials. The project never left the planning stage and was overtaken by a key branch of old printed encyclopedias.
Another early online encyclopedia was called the ''Global Encyclopedia''. In November 1995 a review of it was presented by James Rettig (Assistant Dean of University Libraries for Reference and Information Services)
College of William & Mary at the 15th Annual Charleston Conference on library acquisitions and related issues. He said of the ''Global Encyclopedia'':
He then gives several examples of article entries such as

The user would execute the encyclopedia's software program to see a menu that allowed them to start browsing the encyclopedia's articles, and most encyclopedias also supported a way to search the contents of the encyclopedia. The article text was usually
hyperlinked and also included
photographs,
audio clips (for example in articles about historical speeches or musical instruments), and
video clips. In the CD-ROM age the video clips had usually a low resolution, often 160x120 or 320x240 pixels. Such encyclopedias which made use of photos, audio and video were also called
multimedia encyclopedias. However, because of the
online encyclopedia, CD-ROM encyclopedias have been declared obsolete.
