Home > Resources


The following documents and references are provided as resources for the digitization of both audio-visual and still image digital content.  These have been created and compiled to assist practitioners, students and others, both as a discipline as well as a component of digital conversion projects. These items have been produced by the members of FADGI, and more items will be added as they become available.

While no hard cutoff date was used in selecting guidelines, standards and other documents, they have all been reviewed for current relevance. Because referenced documents may change, please refer to the online version of documents rather than print copies, particularly with regard to standards.

Each of these resources has been developed or recommended by the Audio Visual and/or Still Image Working Group. The resources are listed by working group source and type below. Comments and suggestions are welcome.

FADGI does not review, certify, or endorse commercial products. This includes all software and hardware used to create and manage digital content. If a commercial entity uses the term “FADGI” or references a FADGI resource or document, it has not be authorized by FADGI to do so. FADGI does not maintain lists or other information about commercial products that claim FADGI conformance. All references to commercial products in FADGI documents are examples, and not recommendations or mandates to use those products.
