A unit of information in a bibliographic
record under which a person may search for and identify items listed in the library catalog or bibliographic database. Access points have
traditionally included the main entry, added entries, subject
headings, classification or call number, and codes such as the standard number, but with machine-readable cataloging, almost any portion of
the catalog record (name of publisher, type of material, etc.)
can serve as an access point. In the MARC record, most access points
are found in the following fields (with XX in the range of 00-99):
1XX - Main
entries
4XX - Series
statements
6XX -
Subject headings
7XX - Added
entries other than subject or series
8XX - Series
added entries
In a more
general sense, any unique data element that
serves as a point of entry to an organized file of information. In
files indexed with controlled vocabulary, an access point
may be a preferred or non preferred term.
Also refers to
a physical location where wireless access is available.
