We would appreciate if media where blocked for lending once they have been reserved by a patron but are not on the reservation shelf yet (=they are only on the shelf list in Quria). Would this be possible? We have often cases where patrons bring back media that are reserved by another patron and try to borrow them again just after returning them on the return shelf. If they do so, they are faster than we are with collecting the item from the return shelf and reserving it for the other patron... Thank you!
