Hi I welcomed the introduction of the hours unit in the circulation and fine rules configuration. I have been using a commercial library system that enables reserve books to be borrowed for internal use for two hours from 09:00 to 15:00 Monday to Thursday, after which they are borrowed for overnight use, which means the books become due the following morning before 09:00. However, the Library closes at midnight. On Friday, reserve books are borrowed for weekend use from 10:00 and become due on Monday. I am now almost through with my migration to Koha. However, I do not know how I can configure my reserve books loan rules so that they behave as explained.. May be the introduction of opening time and closing time for item types so that in the calculation of due dates, as with the calendar tool, will not fall due when that particular item type (for example reserve books) is deemed to be "closed" for circulation, could be the solution going into the future. This could be a future functionality request. However, in the meantime, I will appreciate any pointers on how I can configure the reserve books loan rules so that they behave as explained.
