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 [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.

Content for this wiki page is currently being curated by the following team: Nicholas Graham, Project Coordinator, North Carolina Digital Heritage Center [3], 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.

PROJECT PLANNING & MANAGEMENT

This section curated by Nicholas Graham and Lisa Gregory of the North Carolina Digital Heritage Center.

General Resources

The Federal Agencies Digitization Guidelines Initiative (or FADGI) [4] is a collaboratively maintained clearinghouse of information related to digitization, from project planning [5], to digital file formats [6], to technical specifications [7]. 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 [8] produces guidelines for creating digital images of cultural heritage materials; and (2) the Audio-Visual Working Group [9] 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 Society of American Archivists (SAA) [10] provides a useful list of links to sources of information about digitization standards on its website. http://www2.archivists.org/standards/external/123

The UCLA Libraries Special Collections Digital Project Toolkit [11] includes many template documents suitable for planning digitization projects, such as a Digitization Cost Estimate Worksheet [12], a Fair Use Statement [13], a Vendor Decision Matrix [14], Digitization Workflow Guidelines [15], Quality Control Guidelines [16], and more. http://library.ucla.edu/special-collections/programs-projects/digital-projects-special-collections

A number of cultural heritage institutions and professionals have created videos about their digitization work for YouTube [17].

Several professional organizations regularly offer webinars on digitization. Lyrasis [18] includes introductory training as well as more in-depth topics. OCLC often focuses on their own products, but their live and recorded webinars can include helpful information. [19]

Cost Estimation and Planning Resources

The Digital Library Federation [20] Assessment Grouphas developed the Library Digitization Cost Calculator [21] (beta) 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 standard flatbed digitization of archival collections. The calculator is currently undergoing revision and the Assessment Group is now calling for institutions to contribute data to the effort [22]. http://statelibrarync.org/plstats/digitization_calculator.php.

Prior to creating the Cost Calculator, the DLF Assessment Group also put together a Cost Assessment Bibliography with readings and resources on the topic. https://docs.google.com/document/d/1yFWNWonZXHEFagI0A4ujeCl6U7SriJbfmqAgFGLA-Os/edit

The Association of Research Libraries (ARL) [23] developed the Principles to Guide Vendor/Publisher Relations in Large-Scale Digitization Projects of Special Collections Materials [24] 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

The Mountain West Digital Library [25] (a DPLA Service Hub) organized a Digital Services Pricing Task Force, which conducted an environmental scan of prices offered by a number of vendors and DPLA Service Hubs, and instituted a process for establishing common charges across the digitization centers maintained at MWDL partner institutions. The resulting Digital Services Price List provides predictability for costs for basic digitization, hosting, and metadata services offered to libraries, museums, and archives in the MWDL network. http://mwdl.org/docs/MWDL_Digital_Services_Price_List_2015.pdf
