Digitizing Special Formats
This list of resources is curated by the Digital Library Federation for the benefit of cultural heritage professionals planning projects involving the digitization of rare and unique materials. Applicants to the Digitizing Hidden Special Collections and Archives and Recordings at Risk programs of the Council on Library and Information Resources may find these helpful in planning project proposals.
Rather than providing comprehensive coverage, this list includes introductory and reference materials that are good places to begin an exploration of issues of broad import to digitizing cultural heritage materials.
Content for this wiki page is currently being curated by the following team: Nicholas Graham, Project Coordinator, North Carolina Digital Heritage Center, Lisa Gregory, Digital Projects Librarian, North Carolina Digital Heritage Center, and Tamsyn Rose-Steel, CLIR/DLF Postdoctoral Fellow for Data Curation in Medieval Studies at Johns Hopkins University.
If you would like to suggest a resource for inclusion on this page, send your suggestion to DigiWiki@clir.org. The DLF is currently seeking professionals from DLF member institutions who would like to participate in a curatorial group to develop and maintain the content of this page. Prospective volunteers for this group should also send expressions of interest to DigiWiki@clir.org.
Getting Started with Designing a Digital Preservation Plan
This section includes resources that will give an overview of the concepts that a cultural heritage institution will consider as it designs a digital preservation plan for digitally reformatted materials.
