FIELD BY FIELD GUIDELINES
SUMMARY: DELETE FROM NON-YALE CATALOG/VENDOR IMPORT RECORDS (OCLC)
Generally applies to cataloging copy exported from OCLC. Should be used with caution when updating previously cataloged records in Orbis. Check with supervisor if it is unclear whether a local field, a 6xx with indicator 1, 3-9, or a 69x was added by Yale cataloging, especially if the item is held by a special collection; when in doubt, retain.
DELETE Recommended:
  011, 012, 029, 039, 045 (books only),  049, 069, 072,092, 096, 098, 263
DELETE: Required:
  500 (with ‡5), 510 [SERIALS ONLY! 1st indicator 0, 1, or 2], 541, 590, 599
  600, 610, 611, 630, 650, and 651 if 2nd indicator 1, 3-9 (except FAST headings)

USE JUDGMENT:   035 SEE 035 FIELD SUMMARY DOCUMENT
USE JUDGMENT:  Delete if assigned by vendor: 046, 080, 082
USE JUDGMENT:  653: retain for on order and in-process records; delete when record is cataloged.
USE JUDGMENT:  090: retag if LC class; otherwise delete. 099 retain if Yale class; otherwise delete
CAUTION:  If the bibliographic record was cataloged by a Yale library, whether imported from a utility or cataloged on Orbis, NEVER delete local note fields (500 with ‡5, 541, 590) or local access fields (69x, 6xx with 2nd indicator 4 or 7, all 7xx ‡5)
