Bibliography

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.

See List of bibliographies

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