This series contains copies of each and every publication produced by the Section from its inception to the present. Included are items which run the entire gamut of the publication field from directories of recreation and park agencies to studies commissioned by the section on techniques and programs. This series does contain a few publications which were updated at various times and which should, therefore, be rightfully placed in separate series. Since the number is small, however, an exception was made in this instance and all the publications are filed together.
