The permanent exhibition, the most typical form of museum exhibition, has failed to attract repeated visitation, since visitors quickly become familiar with the objects shown. The temporary exhibition evolved as a result for the need of repeated visitation. The temporary exhibition, set up for a period of one to six months, introduces fresh material to the visitor and stimulates his interest. Moreover, it frequently causes him to revisit the permanent exhibition which contains the museum's main assets. This manual, consisting of seven chapters, deals with the temporary exhibit and traveling exhibit. Part I, the Temporary Exhibit, includes three chapters: The Temporary Exhibit in Science Museums, which deals with designing, staff planning, lighting, sound, etc.; Temporary Exhibits in Art Museums, which considers methods, visitors, catalogues, guides, and talks; and Exhibits in the Technically Underdeveloped Countries, which discusses program types. Part II, Traveling Exhibitions, contains the following four chapters: Chapter IV deals with the origin, sources, costs, supervision, assembly, display, and other topics related to traveling exhibits; Chapter V discusses principles of packing; followed by Chapter VI, transportation. Chapter VII, the final chapter, considers insurance policies. An introduction, bibliography and three appendices are also included. (Author/TK)
