Systematic or Enumerative

This kind of bibliography deals with the enumeration and classification of books. It also takes care of the assembling of bibliographical entries into logical and useful arrangement for study and research. A bibliography is a well-maintained list of written, printed or otherwise produced form of civilization. We can define bibliography in relation to books, in practice it is concerned with all printed documents, including those that are brought out but not published. When the records are listed in any order alphabetically, logically, or as per some principle or in a particular order, they are known as a systematic bibliography.

Systematic bibliographies are of various types and can be categorised according to certain characteristics which include:

1. form - physical, intellectual or inner form 
2. language 
3. subject 
4. geographical area covered 
5. time factor/period covered 
6. producing agency 

In other words, the concern is not mere listing of printed documents, especially published documents but with the effective listing of them so that they may be traced readily through authors, titles and subjects; and also by forms and series, wherever required. The systematic bibliography should lead to effective access to information.
