  • definitions, synonyms
  • basic factual information
  • overview or guide to a subject
  • maps
  • statistics, charts, tables

  • Encyclopedia
  • Almanac
  • Atlas
  • Dictionary or Biographical Dictionary
  • Directory
  • Factbook
  • Gazetteer (a geographical dictionary)
  • Handbook
  • Statistics
  • Thesaurus
  • Yearbook
