oclc

identifies the following number as an OCLC accession/record number

dash

Accession/record number of the work in question in the OCLC database/WorldCat

dash (optional)

physical volume, part, number or item count (optional, repeat if necessary)

Applies to multi-part resources cataloged under the same OCLC number (for instance serials or multi-volume works). This part of the file name primarily reflects the count of physical items sent to digitization, as outlined in project documentation or tracking sheets. It does not necessarily reflect the logical structure of a work issued in volumes/parts/numbers.

dash (optional)

image count (optional)

Typically applies to paged content. This part of the file name reflects the image count, not page numbers found in the physical object.

underscore

Type of surrogate file/intended use:

  • am: Archival File (Archival Master)

  • pm: Production File (Production Master)

  • ac: Access Copy

File name extension indicating the file format (for example tif, jpg, wav, mp4, etc.)
