The purpose of this four phase quasi-experimental study was to determine if putting selected books into a display controlled by a theme in a school media center would: (1) increase the circulation of the display books; (2) cause an increase in the circulation of the entire collection; and (3) encourage children to read a type of book they did not normally choose to read. The sample of 100 tagged books was divided into two equal groups, each with 17 fiction and 33 nonfiction books, and each group fitting into a specific theme. Circulation of the tagged books was recorded during the pre-experimental period of 4 weeks, the two successive experimental periods of 4 weeks each, and a post-experimental period of 3 weeks. Each group of books had a turn at being the experimental group in a display while the other group remained in the collection as a control. Circulation data for the entire collection were recorded for the four phases of the study. A questionnaire inserted in the display books and returned with the books was used to determine if the books were read by the user, if liked, if different from the kind usually read, and why the book was selected. A copy of the questionnaire, 12 references, and a six-item annotated bibliography on the library display are included. (Author/MAB)
