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.
- publications mentioned in, or relevant to, a particular work; a bibliography in this sense, sometimes called a reference list should normally appear at the end of any paper in the scientific literature.
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.
