Moreover, after the introduction of the ticket system the unne- cessary delay caused in entering the particulars of a loaned book on a register, etc., is avoided. All that a reader has to do is to go to the rack that contains the book he needs, take it out, and place it at the issue counter along with the borrower's tic- ket and then take it home. It will be exchanged for the ticket. a classified To facilitate the reader to select the book quic- kly it is necessary that the books are arranged in sequence on the racks. A weli classified arrangement of books would thus help to arrange all the books on a specific subject in a helpful manner. Hence there is every chance for a reader to find his or her book without any diffi- culty. Books dealing with a particular subject with correct class number assigned to them should all be found arranged compactly in consecutive rows. This arrangement would save the reader's time consider- ably. It would also increase the use of books. This law would also plead that the library staff should find time to attend to each reader individu- ally in order to save his or her time. For this pur- pose, it is necessary that the time of the staff also should be saved by simplification and standardisa- tion of procedure. Towards this end it would be better that both the card system of record and the system of vertical filing may be introduced in all libraries. This would save the time of the staff to some extent. Further, centralisation of the pro- cesses like classification and catalouging would also relieve the staff to a great extent. This law pin- points the need for maintaining a library catalogue.
