Converting Old FHL Film Numbers to Current Numbers
The Family History Library has used three numbering systems for its films. For an explanation of what each system looked like, see Old Book and Film Nubmers Used by the Family History Library.
This article will explain how to find a current film number from an old number.
To determine what the current number for an old or a red number:  Step 1
Find the old number in the following films or in green books called Microfilm Numbers (List of All Film Call Numbers in the Genealogical Society from 1938-1958). These are arranged by the first film numbers and give the second (red) numbers.
 Step 2
With the red number:
1. Go to the DOS version of the Family History Library Catalog,
2. Select Film/Fiche Search.
3. Type C.
4. Type the old (red) film number.
5. Type the part number if applicable.
6. The current film number will be shown under Converted to Film Number.
 Films with the Old Film Numbers List (Old Locality Film Shelf List): Current Old Film Numbers Film #s
470962 F F.H. 1-2207
F Gen. Hist. 1-11
F Am. Pub. A to F Fla. S2
470963 F Ga. pt. 1 to F La. W2a
470964 F Me. 1 to F N.C. Y2
470965 F N.D. 1 to F Vt. W37a
470966 F Va. Pub. A to F Wyo W2
Example: If you found an old number F Vt. W 25a pt. 2, in the green books (or on film), you would find that the red number was 7079. The part number (pt. 2) would stay the same for the red number. Then go to the old Dos version of the Family History Library Catalog.
