Bringing in extra copies of a title for a book club is one of the few circumstances where we recommend placing call number level holds on items owned by other Interlibrary Connect libraries. Never place item level holds for Interlibrary Connect holds as they will not be filled.
Information on placing call number level holds can be found here.
You may want to monitor call number level holds placed for a book club more closely than you would monitor normal title level holds. If an item is lost or becomes otherwise unavailable Evergreen will not target a different item to fill the hold; in this situation you need to cancel the hold and place a new call number level hold.
