Materials donated to the library are sorted by volunteers and evaluated by staff to see if they will enhance the current library collections or can replace a worn or old copy of an item the library already owns.

Unique or possibly rare or valuable items are set aside for evaluation by a specialist in antiquarian books who recommends what should go into a silent auction to raise additional funds for the library.

Any items that are worn, torn, water-damaged, mildewed or in generally bad condition due to age or wear and tear are discarded.

Items that are not added to library collections, set aside for silent auction or discarded are sold in the Book Sale Room at the library.
