It also considers the use of LC authority records in the database. Specific problems are discussed, including some resulting from LC practices. Nev- ertheless, the presence of the authority records, and especially the conver- sion of about 40 percent of the headings in the bibliographic file, has been of great benefit to the library, significantly speeding up the cataloging operation. An appendix contains guidelines for the cataloging staff of the University of Illinois, Urbana-Champaign in the interpretation and use of LC authority records and converted headings.

In the last year for which figures are available (1979-80), the library added more than 180,000 vol- umes representing more than 80,000 titles. The library is currently cata- loging more than 8,000 titles a month; more than 80 percent of the records for these titles are derived from the OCLC database (Library of Congress and OCLC member copy).

We began to use AACR2 for all our cataloging in November 1979. This early use of AACR2 has led to two consequences.
