Program
Retrospective Conversion
submitted by Ermina Hahn
A program on Retrospective Cataloging was sponsored by the On-Line Biblio-
graphic Services SIS at the 1981 Annual Convention in Washington, D.C., on June 28
at 10:30 A.M. The panel, comprised of Rae Shepherd-Schlecter, SUNY, Cortland;
Albert Wang, OCLC, Inc., and James Larrabee, Berkeley was moderated by Joanne
Scanlon.
Ms. Schlecter, the first speaker, persuasively cited the advantages a library
might expect from accomplishing retrospective conversion. Among these, she listed
integration of functions such as purchase records, interlibrary loans, and circula-
tion, as well as bibliographic functions. These functions will underlie better
service. Conversion will overcome the difficulties of filing and cataloging rules,
will allow more sophisticated searching and lessen the need for cross-references.
Mr. Wang offered an alternative to in-house conversion; namely, contracting
such a project to an outside vendor. He explained that OCLC offers this service
utilizing its extensive database which is now in AACR II. To accomplish this
conversion, the vendor would run a library's shelf list against its database and
for each match would provide a new record. The charge structure from OCLC is based
upon a unique unit charge. Factors influencing this unit charge are such things
as the types of records, i.e., monographic, serial, AV; the language of the
records; the expected hit rate; the percentage of cards with unique identifiers
such as LC card number; and the individual library's editing requirements; that
is, the extent of editing which may be required and the amount of local data
required.
The unit cost, therefore, will vary from library to library but Wang cited
that in his experience it has varied from $.50 to $1.40. If there is no match
for a given record on the existing database, OCLC will input an oliginal record
and the contracting library receives the credit.
Larabee, the last speaker gave details of the conversion program which was
initiated about two years ago at the University of California, Berkeley, Law
Library. Financial sponsorship has been provided by the University Library
System in order to develop the largest possible database for an on-line biblio-
graphic system. This system is not designed as an integrated one to include
