Several user guides are provided for the library users to assist in locating resources in the library network.
The card catalogue ( a wooden cabinet comprising drawers of catalogue cards) for the books acquired by the library before 2002 is still in use; can be found in the first floor of the Library .It provides bibliographic information on all such books available in the library in three different sequences (sets of cards on which information is printed).
- In the alphabetical order of the name of the author ( Author Catalogue)
- In the order of the class number of the book ( Class Catalogue or Subject Catalogue)
- In the alphabetical order of the title of the book ( Title Catalogue)
In addition to these three parts of the catalogue, the fourth part is the Subject Index which is a set of cards that carry classification number of each subject. This index guides the user in tracing a book in the subject catalogue by providing the class number for a given subject.
