Digitizing Special Formats

From DLF Wiki
Jump to navigation Jump to search

This list of resources has been 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 [1] program of the Council on Library and Information Resources [2] 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.

If you would like to suggest a resource for inclusion on this page, send your suggestion to Christa Williford at cwilliford[at]clir[dot]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 Christa Williford.


General Resources

The Federal Agencies Digitization Guidelines Initiative (or FADGI) [3] is a collaboratively maintained clearinghouse of information related to digitization, from project planning [4], to digital file formats [5], to technical specifications [6]. FADGI was launched in 2007 under the auspices of the National Digital Information Infrastructure and Preservation Program (NDIIPP). Two groups of professionals from federal agencies develop FADGI outcomes: (1) the Still Image Working Group [7] produces guidelines for creating digital images of cultural heritage materials; and (2) the Audio-Visual Working Group [8] covers the digitization of analog audio and audiovisual recordings as well as the digital reformatting of born-digital audio or audiovisual content. http://www.digitizationguidelines.gov

The Association of Research Libraries (ARL) [9] developed the Principles to Guide Vendor/Publisher Relations in Large-Scale Digitization Projects of Special Collections Materials [10] in 2010 to help institutions build strong working relationships with commercial partners while creating broad access to their collections. http://www.arl.org/storage/documents/publications/principles_large_scale_digitization.pdf

Working with the Digital Library Federation [11] Assessment Group, Joyce Chapman at the State Library of North Carolina developed the Library Digitization Cost Calculator [12] using data collected by Duke University, the University of Alabama, and the Triangle Research Libraries Network. The tool can help professionals create rough estimates for still image digitization of archival collections. http://statelibrarync.org/plstats/digitization_calculator.php

The NEH operates the National Digital Newspaper funding initiative [16], which offers grants specifically for newspaper digitization. http://www.loc.gov/ndnp/guidelines/

The Center for Research Libraries (CRL) [17] maintains the International Coalition on Newspapers (ICON) [18] database, which contains issue and holdings data for over 170,000 publications dating from the seventeenth century through the present.
