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 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, it should probably not be included on the same bib bibliographic record.
In general, microform guides are non-circulating and are shelved in a library’s reference section. If there are multiple copies of the guide/index, and the decision is made that the additional copy will reside in the stacks, assign an LC call number and create a separate holdings record. Include a public note in the 852: $z Guide to Film ####. These are also non-circulating.
