Finding a matching monographic record in OCLC

When comparing the book in hand to an OCLC record, evaluate the record to determine if it matches your book, using OCLC's "When to input a new record" criteria.

The criteria that may justify a new record are presented below. If your book does not match a record, either search again for a matching record or set aside for original cataloging.

Element Notes
010 LCCN: A difference in numbers may justify a new record. Compare field 245 through 5xx for other differences to justify a new record.
020 ISBN: Absence or presence of field does not justify a new record. A difference in field alone does not justify a new record. Compare fields 245 through 5xx for other differences to justify a new record.
040 ‡b Language of cataloging: Presence of field and subfield indicating a language other than English justifies a new record.
Note: never use a record that indicates a language other than English in 040 ‡b.
1XX Absence, presence or difference in choice or form of 1xx fields do not justify a new record
245 ‡a Title proper: Specific differences in the wording of the title proper justify a new record. For exceptions or minor variations, see OCLC's "When to input a new record."
245 ‡b Remainder of title: Absence or presence of subfield does not justify a new record. To justify a new record, use the criteria under field 245 ‡a
250 ‡a

Edition Statement: The following differences justify a new record:

  • Variation in date designation associated with edition
  • Variation in numbered edition statements
  • Variation in statements indicating a difference in content
  • Variation in statements indicating abridgment, enlargement, etc.
  • Variation in statements indicating "draft," "preliminary," "revision," etc.
  • Variation in statements indicating geographic coverage
  • Variation in statements indicating language content
  • Variation in description among issues of an edition that indicate a difference in content

For minor variations that do not justify a new record, see OCLC's "When to input a new record."

250 ‡b Absence or presence of the field and subfield does not justify a new record; however, a difference may be an indication that a new record is needed.
260 ‡a Place of publication: Difference in place of publication justifies a new record. For variations that do not justify a new record, see OCLC's "When to input a new record."
260 ‡b Name of publisher: Specific differences in the publisher justify a new record. For variations in recording of names that do not justify a new record, see OCLC's "When to input a new record."
260 ‡c Date of publication: Difference in date of publication justifies a new record. For variations in printing or copyright dates that do not justify a new record, see OCLC's "When to input a new record."
264 For RDA records using field 264 in place of 260, use criteria for field 260 above.
300 ‡a Extent: Specific differences in the extent of the item justify a new record. For minor variations that do not justify a new record, see OCLC's "When to input a new record."
300 ‡e Accompanying material: Absence or presence of subfields indicating substantive accompanying material may justify a new record. Compare 5xx fields for actual differences in the absence or presence of accompanying material.

5xx Notes indicating differences in the language, edition, format, or content of the item may justify a new record.
