MARC-8
The MARC-8 charset is a MARC standard used in MARC-21 library records. The MARC formats are standards for the representation and communication of bibliographic and related information in machine-readable form, and they are frequently used in library database systems. The character encoding now known as MARC-8 was introduced in 1968 as part of the MARC format. Originally based on the Latin alphabet, from 1979 to 1983 the JACKPHY initiative expanded the repertoire to include Japanese, Arabic, Chinese, and Hebrew characters (among others), with the later addition of Cyrillic and Greek scripts. If a character is not representable in MARC-8 of a MARC-21 record, then UTF-8 must be used instead. UTF-8 has support for many more characters than MARC-8, which is rarely used outside library data. Technical details MARC-8 uses a variant of the ISO-2022 encoding. It uses escape characters to represent characters beyond the 7-bit ASCII range of characters. It generally uses the same logica ...

ISO/IEC 2022
ISO/IEC 2022 ''Information technology—Character code structure and extension techniques'', is an ISO/ IEC standard in the field of character encoding. It is equivalent to the ECMA standard ECMA-35, the ANSI standard ANSI X3.41 and the Japanese Industrial Standard JIS X 0202. Originating in 1971, it was most recently revised in 1994. ISO 2022 specifies a general structure which character encodings can conform to, dedicating particular ranges of bytes ( 0x00–1F and 0x7F–9F) to be used for non-printing control codes for formatting and in-band instructions (such as line breaks or formatting instructions for text terminals), rather than graphical characters. It also specifies a syntax for escape sequences, multiple-byte sequences beginning with the control code, which can likewise be used for in-band instructions. Specific sets of control codes and escape sequences designed to be used with ISO 2022 include ISO/IEC 6429, portions of which are implemented by ANSI.SYS and t ...

ISO-2022
ISO/IEC 2022 ''Information technology—Character code structure and extension techniques'', is an International Organization for Standardization, ISO/International Electrotechnical Commission, IEC standard in the field of character encoding. It is equivalent to the Ecma International, ECMA standard ECMA-35, the ANSI standard ANSI X3.41 and the Japanese Industrial Standard JIS X 0202. Originating in 1971, it was most recently revised in 1994. ISO 2022 specifies a general structure which character encodings can conform to, dedicating particular ranges of bytes (Hexadecimal, 0x00–1F and 0x7F–9F) to be used for non-printing C0 and C1 control codes, control codes for formatting and in-band instructions (such as newline, line breaks or formatting instructions for text terminals), rather than graphic character, graphical characters.

MARC Standards
MARC (machine-readable cataloging) is a standard set of digital formats for the machine-readable description of items catalogued by libraries, such as books, DVDs, and digital resources. Computerized library catalogs and library management software need to structure their catalog records as per an industry-wide standard, which is MARC, so that bibliographic information can be shared freely between computers. The structure of bibliographic records almost universally follows the MARC standard. Other standards work in conjunction with MARC, for example, Anglo-American Cataloguing Rules (AACR)/ Resource Description and Access (RDA) provide guidelines on formulating bibliographic data into the MARC record structure, while the International Standard Bibliographic Description (ISBD) provides guidelines for displaying MARC records in a standard, human-readable form.

Chinese Character Code For Information Interchange
The Chinese Character Code for Information Interchange () or CCCII is a character set developed by the Chinese Character Analysis Group in Taiwan. It was first published in 1980, and significantly expanded in 1982 and 1987. It is used mostly by integrated library system, library systems. It is one of the earliest established and most sophisticated encodings for traditional Chinese characters, traditional Chinese (predating the establishment of Big5 in 1984 and CNS 11643 in 1986). It is distinguished by its unique system for encoding simplified Chinese characters, simplified versions and other variant Chinese characters, variants of its main set of hanzi characters. A variant of an earlier version of CCCII is used by the Library of Congress as part of MARC-8, under the name East Asian Character Code (EACC, ANSI/NISO Z39.64), where it comprises part of MARC 21's JACKPHY support. However, EACC contains fewer characters than the most recent versions of CCCII. Work at Apple Computer, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

C1 Control Code
The C0 and C1 control code or control character sets define control codes for use in text by computer systems that use ASCII and derivatives of ASCII. The codes represent additional information about the text, such as the position of a cursor, an instruction to start a new line, or a message that the text has been received. C0 codes are the range 00 HEX–1FHEX and the default C0 set was originally defined in ISO 646 (ASCII). C1 codes are the range 80HEX–9FHEX and the default C1 set was originally defined in ECMA-48 (harmonized later with ISO 6429). The ISO/IEC 2022 system of specifying control and graphic characters allows other C0 and C1 sets to be available for specialized applications, but they are rarely used. C0 controls ASCII defines 32 control characters, plus the DEL character. This large number of codes was desirable at the time, as multi-byte controls would require implementation of a state machine in the terminal, which was very difficult with contemporary electron ...

JACKPHY
In library automation the initialism JACKPHY refers to a group of language scripts not based on Roman characters, specifically: Japanese, Arabic, Chinese, Korean, Persian, Hebrew, and Yiddish. Focus on these seven writing systems by Library of Congress, based on sharing bibliographic records using MARC standards, included a partnership between 1979 and 1983 with the Research Libraries Group to develop cataloging capability for non-Roman scripts in the RLIN bibliographic utility. by Susan Morris, ''Library of Congress Information Bulletin'', vol. 66: no. 12, December 2007.

Index (publishing)
An index (: usually indexes, more rarely indices) is a list of words or phrases ('headings') and associated pointers ('locators') to where useful material relating to that heading can be found in a document or collection of documents. Examples are an index in the back matter of a book and an index that serves as a library catalog. An index differs from a word index, or Concordance (publishing), ''concordance'', in focusing on the subject of the text rather than the exact words in a text, and it differs from a table of contents because the index is ordered by subject, regardless of whether it is early or late in the book, while the listed items in a table of contents is placed in the same order as the book. In a traditional ''back-of-the-book index'', the headings will include names of people, places, events, and concepts selected as being relevant and of interest to a possible reader of the book. The indexer performing the selection may be the author, the editor, or a professional ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Zero-Width Non-Joiner
The zero-width non-joiner (ZWNJ, ; rendered: ; HTML entity: or ) is a non-printing character used in the computerization of writing systems that make use of Typographic ligature, ligatures. For example, in writing systems that feature initial, medial and final letter-forms, such as the Persian alphabet, when a ZWNJ is placed between two characters that would otherwise be joined into a ligature, it instead prevents the ligature and causes them to be printed in their final and initial forms, respectively. This is also an effect of a Space (punctuation), space character, but a ZWNJ is used when it is desirable to keep the characters closer together or to connect a word with its morpheme. The ZWNJ is encoded in Unicode as . Use of ZWNJ for correct typography In certain languages, the ZWNJ is necessary for unambiguously specifying the correct typographic form of a character sequence. The picture shows how the code looks when it is ''rendered'' correctly, and in every row the cor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Zero-Width Joiner
The zero-width joiner (ZWJ, ; rendered: ; HTML entity: or ) is a non-printing character used in the computerized typesetting of writing systems in which the shape or positioning of a grapheme depends on its relation to other graphemes (complex scripts), such as the Arabic script or any Indic script. Sometimes the Latin script, Roman script is to be counted as complex, e.g. when using a Fraktur typeface. When placed between two characters that would otherwise not be connected, a ZWJ causes them to be printed in their connected forms. The exact behaviour of the ZWJ varies depending on whether the use of a conjunct consonant or ligature (where multiple characters are shown with a single glyph) is expected by default; for instance, it suppresses the use of conjuncts in Devanagari (whilst still allowing the use of the individual joining form of a dead consonant, as opposed to a halant form as would be required by the zero-width non-joiner), but induces the use of Sinhala script#Cons ...

CJK Characters
In internationalization, CJK characters is a collective term for graphemes used in the Chinese, Japanese, and Korean writing systems, which each include Chinese characters. It can also go by CJKV to include Chữ Nôm, the Chinese-origin logographic script formerly used for the Vietnamese language, or CJKVZ to also include Sawndip, used to write the Zhuang languages. Character repertoire Standard Mandarin Chinese and Standard Cantonese are written almost exclusively in Chinese characters. Over 3,000 characters are required for general literacy, with up to 40,000 characters for reasonably complete coverage. Japanese uses fewer characters—general literacy in Japanese can be expected with 2,136 characters. The use of Chinese characters in Korea is increasingly rare, although idiosyncratic use of Chinese characters in proper names requires knowledge (and therefore availability) of many more characters. Even today, however, some South Korean students learn 1,800 character ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
