description: '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. [from homepage]'
