Library media specialists are often asked when to create a new record in cataloging various editions of the same title for library media center collections. This article, adapted from the new edition of "Catalog It," will provide some hints to answer this question. In some cases, it is easy to recognize when two copies of the same information package warrant two different surrogate records. However, sometimes it is difficult to tell if an item is a different edition or if someone is playing fast and loose with publication data. This is especially evident in books with statements such as, "Book Fair Edition," or "Published by X with permission from Y for school book fairs." AACR defines "edition" for books as, "All copies produced from essentially the same type image (whether by direct contact or by photographic or other methods) and issued by the same entity." Even if it appears to be a different edition, if the publisher is the same as the original publication, then the information package is "not" a new edition and can be added as a second copy to the existing surrogate record. Any time the publisher changes, then, there is a new edition and should create a new surrogate record.
