Please clarify, If there are thousands of books a library is going to place order in bulk how following works can be done through Koha? 1. How duplicate check can be done at the time of entering data by many staffs simultaneously i.e. suppose a staff entered a books in a order and same book is now entered by another staff than is it possible to check duplicate that it has been entered? it may be in a case where many are placing written request to library for purchasing books. 2. Is it possible to enter/choose the requester name at the time of feeding book data so that he can get the alerts as well as reports should also include the requester name while ordering? adding name may be possible in 3.20 i think but many names can be selected not only one (requester) -- *With Regards,Vinod Kumar Mishra,Assistant Librarian,Biju Patnaik Central Library (BPCL),* *NIT Rourkela,* *Sundergadh-769008,* *Odisha,* *India.* *Mob:91+9439420860* *Website: http://mishravk.com/ <http://mishravk.com/>*
