having lost or having been removed from its binding: see also unbound.

The binding has been removed from a book or pamphlet.

Removed from a bound volume. Most old newspapers are disbound, as those not protected from the ravages of time in volumes tend to be found in poor condition. Such papers should exhibit no disfiguring damage or significant paper loss at the spine. Gluing of separation at the spine is a universally accepted practice, as long as it is carried out with an archival quality (q.v.) adhesive. Where the spine or a newspaper has completely separated, re-hinging with archival quality transparent tape is an acceptable solution to this unsightly condition.
