ACCESSING
"Save the Time of the User"
Among the major objectives established for the OCLC Internet Cataloging Project
was the creation of a database of bibliographic records providing access
information for electronic files accessible over the Internet. As important as the establishment of conventional
bibliographic control of Net resources was the integration of these records into local
catalogs, the OCLC Online Union Catalog, and the OCLC FirstSearch service.
In addition to these conventional efforts, the OCLC Internet Cataloging
Project also sought to "test the technical feasibility of providing automated access to
electronic files based on coded access and location information provided in the bibliographic record
(field 856)." This feature has been implemented within InterCat, the project's catalog of Internet
resources, and through NetFirst(tm), a broader, yet related,
collection of selected Net resources. While the InterCat service does offer direct
Internet access to selected resources, its implementation does not use the full functionality of
the browser environment nor does it fully utilize the bibliographic data and information that
has been incorporated within records to provide enhanced access to these and related resources.
Within a browser environment, users of the InterCat database are offered either
forms-supported or non-supported access to a variety of field search
options. These include a 'Subject Words' and a 'Subject Phrases' search option, a 'Basic'
index, and other conventional record data search options (e.g.
'Publisher', 'OCLC Number', 'Publication Year'). These and all fields can be
searched directly, or reviewed and retrieved from a 'Browse Wordlist'.
While subject headings can be searched or browsed within the InterCat database,
and relevant records subsequently displayed, the retrieved records do not have a
hotlink to other resources assigned the same subject heading. Although users can browse through screens of
retrieved record titles, the current configuration does not permit a direct search on
other subject headings assigned a resource from within the record itself.
Users must initiate a separate search option, and execute a new search for
these other subjects. Likewise, while users can browse an alphabetical listing of subject terms or phrases
in the present InterCat database, the current system does not offer a browsable structured thesaurus of
these terms indicating broader, narrower or related relationships between and among
terms or phrases and their associated concepts. In general, this
configuration offers users limited explicit and implicit assistance in
searching or browsing.
Although the InterCat database does include an assigned call number with
the record of each resource, it does not offer directly-searchable or browsable access to an index of these call
numbers. In addition, the current system does not offer a browsable annotated schedule that indicates
the specific subject coverage of a given classification number or hierarchical group.
