TYPES OF BIBLIOGRAPHY

Bibliographies are regarded as most important tools in libraries and documentation centers. This is due to the fact that they allow free flow of bibliographic information on the published literature of all disciplines. Talking about types of bibliographies, most bibliographies are subject bibliographies but there cannot be effective subject bibliographies unless there are wide-ranging and efficient general bibliographies. Besides the subject bibliographies, the national bibliographies, also known as current bibliographies, are very popular as they can be used for searching current and retrospective information. The other types of known bibliographies are the trade bibliographies and the universal bibliographies.
