The Blue Book of Audio-Visual Equipment
Published (1948) by Business Screen Magazine and The National Association of Visual Education Dealers, 845 Chicago Ave., Evanston, 111. 8Y2 X 11 inches, plastic ring bound, 62 pages. Price, $4.50.
Your Blue Book has in a very short time become a standard reference work on audiovisual classroom equipment. It is especially useful to all directors and coordinators of audio-visual education in schools, colleges, universities, and churches. It provides quick information on practically all the standard makes of projectors for any person having the responsibility for the purchase of such equipment. Perhaps it would not be so useful for smaller school systems or individuals who buy in small quantities.
Accuracy of these descriptions of course is not guaranteed by national audiovisual education dealers since they only reprint descriptions and specifications which are supplied by the manufacturers. Prices quoted cannot be relied upon ince prices on this type of equipment fluctuate quite rapidly. The book is issued as an annual.

Look and See, by Colin Beale

Mr. Beale's book contains a great deal of useful information in its 100-odd pages. Although the subtitle of the book is "Visual Aids in the Service of the Church," there is actually very little mention of the adaptation of visual aids for this particular function. It is up to date in discouraging the use of the word "aids" and recommending the word "materials," and it refers to these materials as complementary rather than supplementary as in the older point of view. It contains good diagrams for students of education on the mechanics of projection. It is a wellwritten discussion of all audio-visual materials and equipment with a few outstanding exceptions. It does not do justice to the subject of the making of handmade lantern slides. It devotes only one page to the important topic of the evaluation of teaching films. Two pages are not enough for discussing the reasons why motion pictures are an effective teaching medium. The creation and maintenance by the classroom teacher of a picture file is also slighted. In the bibliographies, many of the newer postwar American books on audio-visual education are missing as are "Educational Screen," "See and Hear," and "Film World" from the list of periodicals. The book has some terms such as diascope and episcope, mute films, and references to 9x/2-nim film and 3V4-inch square slides which are not common in
