Microforms
1. INTRODUCTION
Microforms (microfilm, microfiche, microopaques) are currenty cataloged according to the provisions of AACR2, Chapter 11, LC Rule Interpretations, LC Subject Headings, LC Classification Schedules, and Bibliographic Formats and Standards, Chapter 3.2. Microforms needing original cataloging will now be cataloged under RDA rules. Microforms are generally of two different types, either microreproductions of materials previously published in paper format, or original microform publications. The original publications include microreproductions of material assembled specifically for bringing out an original edition in microform, for example, a microform collection that reproduces previously existing material, but has not itself existed previously as a bibliographic entity.

*Microform copies of printed materials. *Microform copies of printed materials already in our collection should be cataloged on separate records and not added as copies to the print record. Past practice (pre-AACR2) was to add microforms as copies to the print record.
Microfilm Serials going to the LSC, please follow these special instructions -
- All microfilm serials that are going to the LSC and have earlier and/or later titles filmed together on the same reel should have a |z(View for Holdings) call number with the LSC-VIEW location code attached to the bib record for each title.
- In the above case, attach the barcoded item to either the latest title or to the title which has the most issues on the item. For each of the other titles which has issues on that reel, add analytic item records representing the missing issues with the LSC-ANALYTIC location code and using the same call no. as the actual item. Also add a 590 note explaining which reel/record that the information can be found on: "On reel with: <title(s) of records containing the items."
Barcoding and current location. With the exception of microfilms, microforms not barcoded. Microfilm reels are barcoded and items linked to the bibliographic record by Cataloging staff for firm orders and set standing orders, and by Acquistions staff for serial subscriptions. For all microforms, the current location should not be changed to INPROCESS but should remain the same as the home location as microforms are not labeled by the Marking Table. Exception: Microfilm going directly to the LSC has a current location of INPROCESS until the item is processed for the LSC.
