From FamilySearch Wiki

The old GS (Genealogical Society) book and film numbers refer to former catalog numbers.

Old GS Film Numbers[edit | edit source]

Old GS film numbers were five-digit numbers followed by a one- to four-digit part number. Here are several ways to convert the old GS film numbers into the current FS Library film numbers.

  • Search the FamilySearch Catalog by the locality or author of the record on the film.
  • Consult List of all film call numbers in the Genealogical Society from 1938 to April 1958. 1958. FS Library Collection (These books have no call numbers.)
    • These are sorted by location, with individual states in the United States followed by other countries.
    • This will list a 4-digit microfilm call number, which can be converted to a current film number using the "Old microfilm number conversion" charts.
  • Consult Microfilm number index (changed film numbers). 1967. FS Library 026 G286mi.
  • Use the old CD version of the catalog in the DOS version of FamilySearch. This version is available in the FamilySearch Library in Salt Lake City and may be available in a FamilySearch center near you. The center staff can help you convert the number.
