Library Of Congress Control Number
The Library of Congress Control Number (LCCN) is a serially based system of numbering cataloged records in the Library of Congress, in the United States. It is not related to the contents of any book, and should not be confused with Library of Congress Classification (LCC). History The LCCN numbering system has been in use since 1898, at which time the acronym LCCN originally stood for Library of Congress Card Number. It has also been called the Library of Congress Catalog Card Number, among other names. The Library of Congress prepared cards of bibliographic information for their library catalog and would sell duplicate sets of the cards to other libraries for use in their catalogs. This is known as centralized cataloging. Each set of cards was given a serial number to help identify it. Although most of the bibliographic information is now electronically created, stored, and shared with other libraries, there is still a need to identify each unique record, and the LCCN conti ...

Serial Number
A serial number (SN) is a unique identifier used to ''uniquely'' identify an item, and is usually assigned incrementally or sequentially. Despite being called serial "numbers", they do not need to be strictly numerical and may contain letters and other typographical symbols, or may consist entirely of a character (computing), character string (computer science), string. Applications of serial numbering Serial numbers identify otherwise identical individual units, thereby serving various practical uses. Serial numbers are a deterrent against theft and counterfeit products, as they can be recorded, and stolen or otherwise irregular goods can be identified. Banknotes and other transferable documents of value bear serial numbers to assist in preventing counterfeiting and tracing stolen ones. They are valuable in quality control, as once a defect is found in the production of a particular batch of product, the serial number will identify which units are affected. Some items with ...

Hyphen
The hyphen is a punctuation mark used to join words and to separate syllables of a single word. The use of hyphens is called hyphenation. The hyphen is sometimes confused with dashes (en dash , em dash and others), which are wider, or with the minus sign , which is also wider and usually drawn a little higher to match the crossbar in the plus sign . As an Orthography, orthographic concept, the hyphen is a single entity. In character encoding for use with computers, it is represented in Unicode by any of several character (computing), characters. These include the dual-use hyphen-minus, the soft hyphen, the #Nonbreaking hyphens, nonbreaking hyphen, and an unambiguous form known familiarly as the "Unicode hyphen", shown at the top of the infobox on this page. The character most often used to represent a hyphen (and the one produced by the key on a keyboard) is called the "hyphen-minus" by Unicode, deriving from the original ASCII standard, where it was called "hyphen(minus)". ...

Virtual International Authority File
The Virtual International Authority File (VIAF) is an international authority file. It is a joint project of several national libraries, operated by the Online Computer Library Center (OCLC). History Discussions about having a joint international authority started in the late 1990s. After several failed attempts to develop a unique joint authority file, the new idea was to link existing national authorities. This would present all the benefits of a standard file without requiring a significant investment of time and expense in the process. The project was initiated by the American Library of Congress (LOC), the German National Library (DNB), and the OCLC in April 1998 as a proof-of-concept that authority records can be linked. After extensive testing, the VIAF consortium was formed at the 2003 World Library and Information Congress, hosted by the International Federation of Library Associations. on 6 August 2003, and by September it had its own page at the OCLC website. ...

Library Of Congress Subject Headings
The Library of Congress Subject Headings (LCSH) comprise a thesaurus (information retrieval), thesaurus (in the information science sense, a controlled vocabulary) of subject headings, maintained by the United States Library of Congress, for use in bibliographic records. LC Subject Headings are an integral part of bibliographic control, which is the function by which libraries collect, organize, and disseminate documents. It was first published in 1898, a year after the publication of Library of Congress Classification (1897). The last print edition was published in 2016. Access to the continuously revised vocabulary is now available via subscription and free services. Subject headings are normally applied to every item within a library's collection and facilitate a user's access to items in the catalog that pertain to similar subject matter, in order to save time finding items of related subject matter. Only searching for items by 'title' or other descriptive fields, such as 'aut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Standard Book Number
The International Standard Book Number (ISBN) is a numeric commercial book identifier that is intended to be unique. Publishers purchase or receive ISBNs from an affiliate of the International ISBN Agency. A different ISBN is assigned to each separate edition and variation of a publication, but not to a simple reprinting of an existing item. For example, an e-book, a paperback and a hardcover edition of the same book must each have a different ISBN, but an unchanged reprint of the hardcover edition keeps the same ISBN. The ISBN is ten digits long if assigned before 2007, and thirteen digits long if assigned on or after 1 January 2007. The method of assigning an ISBN is nation-specific and varies between countries, often depending on how large the publishing industry is within a country. The first version of the ISBN identification format was devised in 1967, based upon the 9-digit Standard Book Numbering (SBN) created in 1966. The 10-digit ISBN format was developed by the I ...

Books In The United States
As of 2018, several firms in the United States rank among the world's biggest publishers of books in terms of revenue: Cengage Learning, HarperCollins, Houghton Mifflin Harcourt, McGraw Hill Education, Scholastic, Simon & Schuster, and Wiley. History In 1640 in Cambridge, Massachusetts, Stephen Daye produced the first book printed in British North America, the '' Bay Psalm Book''. The American Library Association formed in 1876, and the Bibliographical Society of America in 1904. The national Center for the Book began in 1977. Types * American cookbooks * Astronomy books Bookselling Popular books in the 19th century included Sheldon's '' In His Steps'' (1896). 20th century bestsellers included Mitchell's '' Gone with the Wind'' (1936), Carnegie's '' How to Win Friends and Influence People'' (1937), Spock's '' Common Sense Book of Baby and Child Care'' (1946), Harris' '' I'm OK – You're OK'' (1969), Woodward and Bernstein's '' All the President's Men'' (1974 ...

Authority Control
In information science, authority control is a process that organizes information, for example in library catalogs, by using a single, distinct spelling of a name (heading) or an identifier (generally persistent and alphanumeric) for each topic or concept. The word ''authority'' in ''authority control'' derives from the idea that the names of people, places, things, and concepts are ''authorized,'' i.e., they are established in one particular form. Note: root words for both ''author'' and ''authority'' are words such as ''auctor'' or ''autor'' and ''autorite'' from the 13th century. These one-of-a-kind headings or identifiers are applied consistently throughout catalogs which make use of the respective authority file, and are applied for other methods of organizing data such as linkages and cross references. Each controlled entry is described in an authority ''record'' in terms of its scope and usage, and this organization helps the library staff maintain the catalog and make ...

Accession Number (library Science)
In galleries, libraries, archives, and museums, an accession number is a unique identifier assigned to, and achieving initial control of, each acquisition. Assignment of accession numbers typically occurs at the point of accessioning or cataloging. If an item is removed from the collection, its number is usually not reused for new items. In libraries In libraries, this numbering system is usually in addition to the library classification number (or alphanumeric code) and to the ISBN or International Standard Book Number assigned by publishers. In botany Accession numbers are also used in botany, by institutions with living collections like arboreta, botanic gardens, etc., to identify plants or groups of plants that are of the same taxon, are of the same propagule type (or treatment), were received from the same source, were received at the same time.Jebb, Matthew (1998) ''Cataloguing and Record keeping for Plant Collections'' Retrieved from http://www.botanicgardens.ie/ed ...

Leading Zeros
A leading zero is any 0 digit that comes before the first nonzero digit in a number string in positional notation.. For example, James Bond's famous identifier, 007, has two leading zeros. Any zeros appearing to the left of the first non-zero digit ''before'' the decimal point do not affect its value, and can be omitted (or replaced with blanks) with no loss of information. Therefore, the usual decimal notation of integers does not use leading zeros except for the zero in the ones place, which would be denoted as an empty string otherwise. However, for digits ''after'' the decimal point, the leading zeros between the decimal point and the first nonzero digit are necessary for conveying the magnitude of a number and cannot be omitted (ex. 0.001), while trailing zeros – zeros occurring after the decimal point and after the last nonzero digit – can be omitted without changing the meaning (ex. 0.00100). Occurrence Often, leading zeros are found on non-electronic digital display ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cataloging (library Science)
In library and information science, cataloging ( US) or cataloguing ( UK) is the process of creating metadata representing information resources, such as books, sound recordings, moving images, etc. Cataloging provides information such as author's names, titles, and subject terms that describe resources, typically through the creation of bibliographic records. The records serve as surrogates for the stored information resources. Since the 1970s these metadata are in machine-readable form and are indexed by information retrieval tools, such as bibliographic databases or search engines. While typically the cataloging process results in the production of library catalogs, it also produces other types of discovery tools for documents and collections. Bibliographic control provides the philosophical basis of cataloging, defining the rules that sufficiently describe information resources, and enable users to find and select the most appropriate resource. A cataloger is an individua ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Check Digit
A check digit is a form of redundancy check used for Error detection and correction, error detection on identification numbers, such as bank account numbers, which are used in an application where they will at least sometimes be input manually. It is analogous to a binary parity bit used to check for errors in computer-generated data. It consists of one or more digits (or letters) computed by an algorithm from the other digits (or letters) in the sequence input. With a check digit, one can detect simple errors in the input of a series of characters (usually digits) such as a single mistyped digit or some permutations of two successive digits. Design Check digit algorithms are generally designed to capture ''human'' transcription errors. In order of complexity, these include the following: * letter/digit errors, such as l → 1 or O → 0 * single-digit errors, such as 1 → 2 * transposition errors, such as 12 → 21 * twin errors, such as 11 → 22 * jump transpositions errors, ...

Identifier
An identifier is a name that identifies (that is, labels the identity of) either a unique object or a unique ''class'' of objects, where the "object" or class may be an idea, person, physical countable object (or class thereof), or physical mass noun, noncountable substance (or class thereof). The abbreviation ID often refers to identity, identification (the process of identifying), or an identifier (that is, an instance of identification). An identifier may be a word, number, letter, symbol, or any combination of those. The words, numbers, letters, or symbols may follow an code, encoding system (wherein letters, digits, words, or symbols ''stand for'' [represent] ideas or longer names) or they may simply be arbitrary. When an identifier follows an encoding system, it is often referred to as a code or id code. For instance the ISO/IEC 11179 metadata registry standard defines a code as ''system of valid symbols that substitute for longer values'' in contrast to identifiers wi ...
