Authority includes the qualifications and reputations of the authors and publishers. It also asks the selector to consider whether this is a new work or a revision of a previous work. Scope considers whether the text covers what it claims to cover. Treatment follows from scope and requires the selector to examine accuracy of information and identify biases and how well the authors balance the coverage of the subject. Treatment also considers the level at which the work is written.
Arrangement covers the actual order in which the information in the text is presented.
It also includes an examination of the quality of the indexing. Format includes such points as the quality of illustrations, binding, and the materials used in the work. Special features covers the factors that make this work unique. Unless something in the announcement runs up a red flag in your mind, don't worry about it. If the title was produced by a publisher covered by our approval plan vendor, the selector will get a chance to examine the work when it appears as a firm order item on the approval plan shelf.
