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 called 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.).

Book number

A book number is composed of letters from the author's name or letters from the title main entry and numbers. There are several systems for creating book numbers.

Boolean operators
AND, OR, and NOT. Used to combine search terms. AND finds only records that contain both terms. OR finds records that contain either term. NOT finds records that contain the first term but not the second term. Combining search terms produces more precise and manageable search results.

subject
The topic that is the main focus of the content of a library resource.

subject headings
The most specific word or phrase that describes the subject, or one of the subjects, of a work, selected from a list of preferred terms (controlled vocabulary) and assigned as an added entry in the bibliographic record to serve as an access point for retrieving records in a database.

A subject heading may be subdivided by the addition of subheadings (example: Libraries--History--20th century) or include a parenthetical qualifier for semantic clarification, as in Mice (Computers).

The use of cross-references to indicate semantic relations between subject headings is called syndetic structure.

The process of examining the content of new publications and assigning appropriate subject headings is called subject analysis.

whole phrase search
All words, numbers, or character strings used to initiate a search for an entire indexed field in records. To enter a complete search string using a "command line" search in Connexion, use a whole phrase index label in the format xxw= (where xx represents the label).

Note: FirstSearch/Resource Sharing supports only one whole phrase index—Subject. This index label has a different format; see example below.

For a whole phrase search, enter all field data or truncate using an asterisk.

Examples:

  • To search for a subject field in Connexion, type suw=library science computer* (field data is truncated).
  • To search for the same subject field in FirstSearch/Resource Sharing, type sa=library science computer* (field data is truncated).
wildcard (# or ?)
A special character used to represent one or more characters in a search term. The pound sign (#) represents a single character, and the question mark (?), alone or with a number, represents zero or more characters. Wildcards must be preceded by at least three characters in a term. Example: wom#n retrieves women or women; col?r retrieves color or colour. See also truncation (*).

word indexes

Example: To search for an OCLC control number, type no:10998406 (or #10998406 or *10998406).
