Choosing OCLC Records

<< Back to Cataloging
<< Back to Miscellaneous

If multiple records describe the same bibliographic item, prefer (in this order):

  1. Has 040 DLC $c DLC (should have "D" in right hand column on hit list)
  2. Avoid records with 040 ǂe or ǂb if possible
  3. Has 042 field
  4. In Fixed fields: Elvl: (top of second column). See table below for priority order
  5. If multiple records at same priority, choose record with greatest number of holdings attached
  1. Look for records with the fullest amount of information, subject headings, and LC call number
  2. For multi-volume sets without individual titles for each volume, look for a single record

Before deciding that multiple records do describe the same bibliographic item, check for:

  • Same title, author, edition, publisher, series
  • Presence of ǂh [microform] or ǂh [electronic resource], etc., in the 245 field
  • Presence of 533 note indicating record is for a photocopy or microform of the original

Encoding levels (Elvl):

  • _ (blank) -- Very good
  • I -- Good
  • K -- So-so (varies)
  • M -- Poor
  • 8 -- Bad
  • 3 -- Bad
  • Other -- Rare, usually bad
