There are many types of bibliographies and the leading bibliographies defer slightly in the names they assign to its various branches. There are primarily, of two kinds.

1. General bibliography;

1. General Bibliography : It comprises :

• i. Universal Bibliography (through earlier it was only at an ideal, presently the technology has almost made it a practical proposition);
• ii. Language bibliography;
• iii. National bibliography; and
• iv. Regional bibliography.

2. Special bibliography : This includes :

• i. Subject bibliography;
• ii. Author and bio-bibliographies;
• iii. Bibliography of forms of literature;
• iv. Bibliography of materials of particular periods;
• v. Bibliographies of special categories of literature; and
• vi. Bibliographies of specific types of materials.

Current and retrospective bibliographic, primary and secondary bibliographies and bibliographies of bibliographies are other categories. But every type is not strictly called a bibliography. For example, a list of periodical articles is an index. Similarly, we have concordances, calendars, wiscographies, pictographies, directories and so on..
