I found some more of the ALL ARABIC CHARACTERS mystery, this time in the form of books actually on the shelf, somehow having call numbers, but no other metadata in the catalog except for that generic title. Maybe we used to have cards for them and the description got lost in that retrospective conversion?
They are now cataloged. Maybe somebody else will be able to discover them now!
