We will need to think about how Collections relate to circulation policies at your library. Circulation under the Library Service Platform will be driven by Collection codes. So, the next phase will involve syncing Circulation (Aleph) Item Status for items within the same collection.
This is less of a concern for items of different material types. One can make exceptions based on material types. However, if you have items of the same material type (eg books) then you may want to review what is in place.
The Aleph report XX_cltn_count provides overall counts of items by sub-library, collection, item status, and by material type. This report will run four times per year so that it is always in Task Manager. (Other listings of a specific collection can be requested by work order.)
For example, a library has a collection with some books that have an initial loan period of three days, along with books that have an initial loan period of 7 days. Maybe it would be better to have a ‘reserves 3 day’ collection and a separate ‘reserves 7 day’ collection. (Some libraries already make this distinction.) Alternately, a library might eliminate one of those initial loan periods. Maybe that collection rarely circulates books for a ‘3 day’ loan?
EDIT: Please look at the June 2018 Cataloging Committee meeting minutes for a more detailed explanation.
