A bibliography is an overview of (almost) all publications in some category:

  • works of some author;
  • publications about some specific subject;
  • publications published in some specific country;
  • publications published in some specific period.
A bibliography tries to give a complete overview of the (important) literature in its category. This is opposed to a library catalog, which only describes items actually found in the library. However, some national libraries' catalog also serves as a national bibliography, as (almost) all publications of this country are contained in the catalog.

Bibliographies can be sorted in several ways, similar to library catalogs.
