PROOF COPIES
(Approved for use April 2, 2003)

Proof copies are pre-publication printings of books that are usually available later as a trade edition. Often the proof will be an imperfect iteration of the actual book. Since they are roughly equivalent bibliographically to the published edition, they are cataloged as copies as much as possible. The following steps should be followed in processing proof copies:
 
 

1. Search Orbis for the author and title. Be aware that the title may have changed between the proof and the published item.
 

2. If there is already a copy of the published edition in Orbis, add the proof as another copy with 590 notes about the proof, including variations in title, subtitle, pagination, and size. Add a 655 7 Proofs (Printing) divided by place and year with ‡2 rbpri ‡5 CtY-BR at end.

3. If there is no copy of the published edition in Orbis at the time of cataloging, or it is not clear that there is a copy of the published edition in Orbis, catalog the proof in a separate record as a printed monograph. Type of record code should be "a" and bibliographic level "m." Often there will be copy available in the LC database or in RLIN or OCLC on which to base the record. Use general notes (500) to indicate that it is a proof. Add a 655 7 Proofs (Printing) divided by place and year with ‡2 rbpri, but do not add ‡5CtY-BR at end, as the record as a whole describes the proof copy.

4. If the proof has been cataloged in a separate record, and we later get the published edition, the proof copy may be added on to the record for the published edition with an appropriate 590 note and 655 and the separate record for the proof deleted, but this is optional.
 

5. In the rare case where the proof and published edition are significantly different (i.e. the title proper differs), make two bibliographical records.  In case of doubt, use one record.
