Union List glossary

AACR2: Anglo-American Cataloguing Rules, Second Edition. The national/international standard for cataloging library materials. The rules are "designed for use in the construction of catalogues and other lists in general libraries of all sizes. ^ The rules cover the description of, and the provision of access points for, all library materials commonly collected at the present time." The rules are maintained by the Joint Steering Committee for Revision of AACR and published by the American Library Association, the Canadian Library Association, and the Library Association.
address: Words, numbers, or symbols that designate a physical or virtual location. Examples: street numbers and names, countries, e-mail addresses, URLs.
ANSI: American National Standards Institute. A nonprofit non-governmental organization composed of representatives from business and professional organizations that acts as the repository for various voluntary standards. See also NISO.
ANSI/NISO Standards for Holdings Data: The standard for holdings data exchange, providing a normative arrangement of data in records so that the data and records can be efficiently shared among users. Current ANSI/NISO standards for holdings data are documented in Holdings Statements for Bibliographic Items (ANSI Z39.71 1999). See also Level 1; Level 2; Level 3; Level 4.
archive record: The bibliographic record OCLC creates and stores that contains local changes made by an institution to the master record. Archive records are a complete history of an institution's OCLC cataloging activity. OCLC uses archive records to create offline products—catalog cards, magnetic tape cartridges of records, electronic files of records. Note: Union list data entry does not create an archive record.
ASCII: American Standard Code for Information Interchange. A standard computer character code set, consisting of alphanumeric characters, punctuation, and a few control characters (such as a carriage return). Each ASCII character consists of 7 information bits and 1 parity bit for error checking.
assigned search key: A string of characters assigned to an item by an agency which can be used to retrieve the record for that item.
authorization level: See authorization mode.
authorization mode: Defines a range of tasks that can be performed when logged on to a service.
authorization number: Number assigned by OCLC to authorize use of OCLC services. Usually used in conjunction with a password. See also password, default system, default holding library code.

bibliographic information: Details about an item that are sufficient to identify it for the purpose of retrieval are placed in a specific format that describes one item in a collection. Examples: author, title, publisher, publication location, edition, series title, and notes.
bibliographic record: Contains the cataloging information that describes the physical format and intellectual content of a single entity (a book, video, computer file, CD, etc.). Catalogers create records by encoding this information using tags, indicators, and subfield codes in a standard format, MARC 21 (MAchine-Readable Cataloging). Each record is divided into fields (author, title, subjects, etc.) Fields are subdivided into subfields (place of publication, publisher, etc.).
brief list: The default display of results from interactive searches using CatME, Arabic, CJK, or from searches using Passport when two to five records are retrieved. Each entry gives a two- to six-line description of a record, containing descriptive fields, OCLC control number and other information.
Browse: Command used to send a title phrase search.

call number: A set of letters, numerals or other symbols (in combination or alone) used by a library to identify a specific copy of a work. A call number consists of the class number and book number (or Cutter number).
Cataloging Agent mode: An authorization mode that allows the Cataloging Agent of a resource-sharing group to process cataloging records on a member's behalf. Agents process unresolved records from the group's batchloading activity.
chronology: Types of dates used by publishers to identify the individual bibliographic unit of a serial, for example, date of coverage, date of publication, or date of printing.
classification number: The part of a call number, usually a combination of letters and numbers, used to classify library resources by subject area.
CODEN: The Chemical Abstracts Service assigns six-character codes to serials. The first five characters have a mnemonic relationship to the serial. The last character is an alphabetic or numeric check character. For example, AISJB6, CADIDW.
communications format: In machine-readable cataloging (MARC), the standards for representation and exchange of data in machine-readable form. In the USA, this is an implementation of an ANSI standard. MARC 21 Format for Bibliographic Data (formerly called USMARC) is an implementation of ANSI standard Z39.2. OCLC-MARC is an implementation of MARC 21 that conforms to the ANSI standard. Standards provide a common way of organizing machine-readable records so that they can be easily exchanged among users.
completeness: An indication of how much of a published run of a serial is held. Completeness is indicated in ranges, for example, Complete (95% 100% held), Incomplete (50%-94% held), Scattered (less than 50% held).
conference name: All or part of the name or title of a conference. A conference name could also be included in a title, abstract, notes, or text of a library resource. Examples: names of meetings, exhibitions, expositions, festivals, athletic contests, scientific expeditions.
continuing resource: A bibliographic resource that is issued over time with no predetermined conclusion. Continuing resources include serials and ongoing integrating resources.

default holdings displays: The system responds to an unqualified Display Holdings (dh) command with an all, regional, or state list of holdings depending upon the number of holdings available.
default system: The OCLC system you are in when you log on. Each authorization number and password has a default system. See also authorization number, password.

fill character: A black box or vertical bar in workforms that represents content that must have valid data.
fixed field: In OCLC-MARC, the field in which mnemonic labels identify elements that contain coded information for describing the item and the record. Each element has a fixed length. The fixed field is the OCLC-MARC format's combination of various MARC 21 control fields.
