Material selection and preparation

Creating your Inventory

Content provider will organize content and create an inventory of candidates for digitization. 

The inventory is used during digitization to track progress and is viewable by Content Providers.  This will be a means of keeping stakeholders up to date on project progress.

  • The inventory is used to identify objects and match them to the correct unique identifier or MMSID during digitization in the lab.
  • The lab cannot digitize and name files without the correct file names or ingest content into the repository until the metadata and inventory are reviewed and approved.

      • recordseries#_box#_folder#002.tif
    • access (folder)
      • recordseries#_box#_folder#-001.jp2 (file level)

File naming rules

  • No duplicate Unique Identifiers ANYWHERE in the collection
  • No special characters at all including dots, commas, slashes, ampersands, number signs
  • No spaces
  • Underscores separate rs, box, folder, item and date.  Please leave text in the file name in one string with no spaces or special characters
  • Dashes are used at the end of the files names to serialize files.  This is used to automate packaging for our repositories
  • ALL under case

Physical Object dropped off for digitization require the follow:

Archival Material

  • identifying record series, item titles, boxes, folders, item numbers  on the object
  • This identifying info corresponds with metadata 

Catalogued Material

  • Catalog records must be updated and correct.


Metadata for Collection

if the content is hosted in the Digital Library, the metadata librarian will help content providers select or create a metadata profile for the collection.  Once the appropriate profile is created, a Google sheet to the profile is provided. The content provider will populate the fields.
