The card catalogue ( a wooden cabinet comprising drawers of catalogue cards) for the books acquired by the library before 1990 is still in use; can be found in the ground floor of the Library .It provides bibliographic information on all such books available in the library in three different arrays (sets of cards on which information is printed):
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.
