This Resource Letter has been prepared as a project of the AAPT Committee on Apparatus for Educational Institutions. It represents a response to questions raised at the 1978 winter meeting in San Francisco concerning sources of information on lecture demonstrations. Thus, this letter is aimed more at readers who have recently become interested in lecture demonstrations, rather than those who are already familiar with the literature. While the authors have examined a great deal of material, and have had help from many people, there are always materials which have been overlooked. Therefore, we earnestly request that any reader with suggestions or corrections please communicate with the authors so that they may be included in any future updating. Because of the introductory scope of this Resource Letter, we have not included all of the resources that are available. Most foreign works, books known to be out of print, items having small circulation, and textbooks and earlier editions bearing differing titles have been excluded. The reader may refer to the annotated bibliography by John A. Davis (Sec. I B5) for a more extensive listing of the literature. When possible, the annotations are followed by one or more reviews so that other opinions can be consulted.
