Hi, Unfortunately, I have not received any suggestions for my previous query and re-posting my question again. Now, I would like to know, How Book Bank and General stocks are maintained at least in Indian Libraries using Koha ? Since, Both Special Category Students and General Students have stocks and different rules for borrowing books. How are the books cataloged for these stocks. Please share your best practices. Need Suggestions for : New Item Type or New Koha Instance. Background- Our Library has following scenario : Patrons: categorized as: 1. Regular (General) Students & 2. Backward Category Students. Collections: Two set of collections are maintained, 1. General Stocks - for ALL Students. (including backward category) 2. Book Bank ( Special Collections ONLY for Backward Category Students) Circulation Rules: 1. Regular Students can borrow books only from General Stocks but not from Book Bank. 2. Backward Category Students can barrow books from both General Stocks and Book Bank Currently, check-in/check-out is by providing separate backward student id card along with regular common id card. My Questions is: Can above said Circulation criteria be fulfilled either by creating a new Item Type - "Book Bank" and adding records to it, along with default item type : Books and then create a circulation rules for both the item types. OR New Instance of Koha (separate database) for Book Bank Library to be created (along with existing one for general stocks)? At present, I have completed updating bibliorecords for the General Stocks and used to issue-return books from General Stock (for Regular + Backward students). But, I am not sure about, proceeding for accommodating only backward students category for getting books from Book Bank Library through koha. Your suggestions are valuable for me and much appreciated. with thanks Satish MV Librarian Govt. Engineering College, Hassan.
