CORRELATED LIST OF VISUAL AIDS 



The following list of 16-mm. motion pictures and 35-mm. filmstrips 

 can be used to supplement some of the material in this book. These 

 visual aids can be obtained from the producer or distributor shown with 

 each title. (The addresses of these producers or distributors are listed 

 at the end of the bibliography.) In many cases these visual aids can 

 also be procured from your local film library or local film distributor. 



The running time (min) of the film and whether it is silent (si) or 

 sound (sd), filmstrip (FS) or color (C) are listed with each title. All 

 those not listed as color are black and white. 



Each film has been listed only once, usually in the first chapter to 

 which it is applicable. However, in many cases it can be used advan- 

 tageously in several of the other chapters.
