An Ex- Library Book is the least desirable book in book collecting terms. The term is used for books that once belonged to a library. Ex – Library books are generally unattractive, as they have usually been stamped, taped, glued or had a card pocket glued to them. The books have often been damaged by the patrons of the library themselves. In this latest artist’s book Sara MacKillop compiles these remnants alongside diagrams and images linked to library systems.
