Hello Elizabeth
You were thorough! Fortunately we have only one collection, which makes it
easier. Thanks for taking the time to reply.

>Greetings - the Library of Virginia has digitized numerous collections
>of photographs and original documents.
>
>We first examine the physical arrangement of the collection, then
>complete an extensive analysis of any existing naming/numbering schemes.
>
>These vary from straight accession number schemes, topical, geographical,
>chronological, none, etc.
>
>We also carefully document any anomolies within these schemes. This is
>important to predict how to structure the file naming conventions to
>accomodate items that crop up that don't neatly fit with the rest.
>
>We nearly always incorporate some iteration of these existing schemes
>in our file naming conventions for the collection.
>
>There may even be multiple file naming conventions within one collection,
>depending upon the nature of the materials.
>
>Here is one example:
>
>For our Virginia Historical Inventory Project (http://eagle.vsla.edu/vhi)
>we had three different types of materials - photographs, maps, and
>survey report documents - the latter being on microfilm.
>
>The file naming convention for the documents:
>
>/VHI/R/01/00001.tif
>/VHI/R/01/00002.tif
>
>Where /VHI is the name of the collection
>/R indicates that it is a report page
>/01 indicates that the report page exists on Reel #1 of the microfilm
>/00001.tif is the number sequentially and automatically assigned to the
> image by the microfilm scanner
>
>The file naming convention for the photos:
>
>/VHI/P/01/0001.jpg
>/VHI/P/01/0002.jpg
>
>Where VHI is the name of the collection
>/P indicates that it is a photo
>/01 indicates that the photograph is associated with a report that
> exists on Reel #1 of the microfilm
>/0001.jpg is the number sequentially assigned by the cataloger
>
>
>We determined that there were FEWER than 100,000 report images, so
>we reserved 5 digits in the filename (/00000.tif).
>
>We determined that there were fewer than 10,000 photograph images,
>so we reserved 4 digits in the filename (/0000.jpg).
>
>If you are not CERTAIN of the number of photos/pages, etc. within
>the subset of the collection you are naming, it is better to provide
>the cushion of an extra digit in the filename, just in case!
>
>This also ensures a logical organization on the server:
>
>/VHI
> /Reports
> /Reel #
> /Image number
> /Photos
> /Reel #
> /Image number
> Maps
>
>I have numerous other examples - let me know if you would like
>additional information.
