- For material that has been described bibliographically, the directory name containing the image files should be the bibliographic ID number, the 001 field in the catalog record: 6124186 (bib ID)/00000001.tif (file names); i.e. 6124186/00000001.tif. An intermediate directory is appropriate for multi-volume items. For example: 6124186 (bib ID)/01 (volume number)/00000001.tif (file names). Directory names should not have punctuation or spaces.
- For archival materials described in a finding aid, the directory structure generally follows the finding aid structure wherein . The variation is that the collection code and component identification numbers are separated by an underscore and are used in place of a bib ID. For example: C0744 (collection code)/c002 (component ID)/00000001.tif (file names) , i.e. should be organized as C0744/C0744_c002/00000001.tif.
Some materials, such as audiovisual materials or ephemera, may be named corresponding to a barcode or other unique identifier assigned to each physical asset. This may also include indicators about the side (for bilateral media) and derivative status appended at the end. For example: 32101047381338_1_pm.wav (where 32101047381338 = barcode, 1 = side 1, pm = preservation master, and .wav = file extension).
