Whenever possible the guide/index to a microform set should be added to the bibliographic record for the set. If, in a cataloger’s best judgement, the guide/index is better served by an individual bibliographic record, linking fields must be added to both the microform and guide/index bibliographic records to ensure mutual discovery. For example, if the guide was not originally issued as part of the microform set, or was created and published by a different entity, perhaps it should not be included on the same microform bibliographic record.
In general, microform guides are non-circulating and are shelved in a library’s reference section with the microform accession number. If there are multiple copies of the guide/index, and the decision is made that the additional copy will reside in the stacks, assign it an LC call number and create a separate holdings record. Include a public note in the 852: $z Holdings notes sectionof theHoldings record saying Guide to Film ####. These are also non-circulating.
