Microforms call numbers are listed in the “Red Book” called “Microforms, CD-Roms, DVD-ROMS Numbers” kept at Lucy deGozzaldi's desk.
Assign consecutive accession numbers to microforms as follows:
* Microfilm A
All periodical records
All serial records
Population census publication sets (both monographic and serial) published by Research Publications
* Microfilm D:
Large government document sets (United States and Massachusetts only)
U.S. Dept. of State. Records of … (from the U.S. Archives)
Dispatches from American embassies and consuls (usually from U.S. Archives)
Note: Series D Microfilm is to be used for any U.S. governmental type series, including large sets of diplomatic papers, census of any specific year, etc.
This series has also been used for some state documents, such as the Massachusetts legislative records, etc.
There are a variety of items in the general series which appear to be in categories that should have been placed in the D series.
* Microfilm (Plain number only):
Confidential records of the U.S. Dept. of State
Other governmental records
U.S. Presidential records
All microforms are now cataloged to the W.E.B. Du Bois Library. Formerly, microforms were cataloged to the former three branch libraries: Music Library, Morrill Biological Science Library, and the Physical Sciences and Engineering Library. Former science microforms call numbers are prefaced by “S”. For example Microfiche S221, which distinguishes it from Microfiche 211, which was a Du Bois collection. This is an important distinction to bear in mind when looking for microforms, as the “S” series and regular series are in different cabinets. Music Library microforms have been incorporated into the Du Bois numbering scheme.
