About the format descriptions
The digital content format descriptions accessible here provide specific information about individual formats and their characteristics. Each description provides moderately detailed information and citations. Planned for inclusion are a wide variety of formats: file formats, file-format classes, bitstream structures and encodings, and the mechanisms used to compress files or bitstreams. Inclusion of a description for a format does not imply that the format is preferred or acceptable for Library of Congress collections. For more information, see the Recommended Formats Statement. Although presented here in HTML format, the descriptions are created in XML, and information about how to download the XML versions is presented here.

Descriptions are drafted and added to the site individually rather than on a scheduled basis. The compilers encourage persons with specialized knowledge to review and comment on the descriptions. Please use this contact form to provide comments.
