"MUSTIE" Misleading – information may be factually inaccurate or obsolete. Unpleasant – refers to the physical condition of the book, may require replacement.

"MUSTIE" Misleading – information may be factually inaccurate or obsolete. Unpleasant – refers to the physical condition of the book, may require replacement. Superseded – book been overtaken by a new edition or a more current resource. Trivial – of no discernible literary or scientific merit; poorly written or presented. Irrelevant – doesn't meet the needs and interests of the library's community. Elsewhere – the book or the material in it may be better obtained from other sources. Man, I just disagree with the premise of removing books for any of these reasons. The only one that I can see being good is "unpleasant", in which case the book should just be replaced with a new copy.
