Invincibility of the liberation movement / Boris Ponomarev. (OCLC #16541895)
An OCLC record very closely matched the piece I had in hand; the only difference was that it had 37 pages, where the 300 ǂa said “27 pages”. Had there been other differences I would have thought the record represented a distinct item, but I followed the guidance on when to create a new record:
Differences indicative of a distinct bibliographic item usually occur in more than one field. If a difference occurs in a single field, determine whether there are two separate bibliographic items with only one significant difference or whether the difference is an error or a difference in opinion. If in doubt, use the existing record.
The font used for page numbers is pretty thick, so I can see how the cataloger could have made this mistake. I corrected the master record and added our holdings.
