106. COMPLETELY REVISED EDITION

An edition of a work, other than the first, which has been completely re-edited and overhauled from the standpoint of over-all coverage, space allotment, illustrations, etc. The entire text of a "completely revised edition" has been scrutinized critically and in detail by competent authorities, and every unit either authenticated or revised as necessary to make the complete work adequate, accurate, and up to date. Under programs of continuous revision as practiced by most encyclopedia publishers, the term "completely revised edition" is seldom justified and should be used only in those cases where the entire work has been re-edited and reset.

See also Authenticate; Up-to-Date.

107. CONTINUOUS REVISION

The making of major and minor changes in the content of a work from printing-to printing. Such changes-are usually made (in a regular planned schedule but-frequently include those occasioned by developments in important or "live" fields. Most "continuously revised" works have at least one printing with revisions each year.

112. ENLARGED EDITION

An edition of a work, subsequent to the first, to which material has been added either by incorporating new subject matter or by more extensive treatment of some subject areas previously covered. Technically, any amount of expansion of a work would entitle it to be called an "enlarged edition." Practically, however, and in the interest of fairness to the prospective purchaser, a work should not be represented as an "enlarged edition" unless the additions are of substantial amount and importance. Best practice urges, therefore, that those works incorporating additional material of relatively small amount or of minor significance to the general public be described variant "printings" (or when appropriate, variant "issues") of a basic edition.

122. NEW EDITION

An edition of a work, subsequent to the first, which has been considerably revised in particular subject areas and/or particular categories of information, such as statistics or maps. Technically speaking, even minor change in a book or set makes it different from its immediate predecessor and, therefore, a new edition. However, practically speaking from the standpoint of the public, the term "new edition" connotes considerably more than minor change. In best practice, therefore, "new edition" may be used to describe a work even though it is neither "completely revised" nor a "major revision," but "new edition" should be reserved for those works in which some major features have been completely overhauled and which contain a proportion of completely revised or new material on a scale well above the usual continuous revision program. "New edition" should not be confused with such descriptive phrases as "new work," "new encyclopedia," "completely new (title)," etc.
