Appro. 200 books on one side of the shelf. Regarding Catalogue cabinet you must insist that a PC given to the library to make entry of records. In these days of library automation and networking no new library should go for old method of catalogue cards and filing. UGC(INFLIBNET) wants to network all university and college libraries and may be want to find out how forward looking you are. About your approach to library management. However, you can also calculate the no. of cards that can be held in a tray, and give an second answer in continuation to the online catalogue. All the best, Gayathri Sen
