EX-LIBRARY / EX-LIB
Also EX LIB. Deaccessioned from a public library or collection. These books will have some or all library markings such as call numbers on the spine, pockets or slips at rear, ownership stamps, and similar. In general, these markings detract from the value of a book. Further, care should be exercised to determine that the book has actually been withdrawn from the library (especially for books with substantial value). Libraries sometimes mark books so deaccessioned as withdrawn, but practices vary widely between institutions.
