----------------------------Original message---------------------------- Map friends: Some information for those of you who use OCLC. 1. The Library of Congress recently assigned a new source code for use in subfield $2 of field 072 (Subject Category Code). This code can be used immediately in OCLC and will be added to the various versions of the OCLC-MARC Code Lists (paper, PRISM Help and web) in future revisions. For an example, see #10676271 (83-80975). lcg Table IV "Table of subject subdivisions" in Library of Congress classification schedule: Class G (Washington, DC : Library of Congress). 2. The following Technical Bulletins were recently distributed to users: --Technical Bulletin 218 (Bib Notification)--July 1996 (This TB describes a cataloging maintenance service that makes upgraded cataloging records available to institutions that have previously received--and added holdings to--a less-than-full-level bibliographic record in the OLUC.) -- PRISM EUR-OP Resource File--July 1996 (This TB describes a new resource file of documents and how to access it from PRISM. The EUR-OP files contains records for documents which are published by the Office of Official Publications for the European Communities.) 3. On August 11, 1996, OCLC invalidated the following elements or codes for use in PRISM Cataloging: Value *c* for Publication and copyright date in DtSt. Value *t* should be used instead. Value *c* should now only be used on serials to indicate *Serial items currently published*. Value *d* for Detailed date in DtSt. Value *e* should be used instead. Value *d* should now only be used on serials to indicate *Serial item ceased publication*. Field 211 (Acronym or Shortened Title). Field 246 should be used if appropriate. Field 214 (Augmented Title). Field 246 should be used if appropriate. Scans have been run on the obsolete values *c* and *d*. 555,695 records were converted in April, 1,406 were converted in June, and 611 were converted in August.. Fields 211 and 214 were manually corrected in March. Only 91 records were changed. Final scans will be run later this year. Ellen Caplan OCLC, Inc.
