COMPLETE COLLECTION. 1982 Reprint. Micropaedia -volumes I-X. Macropaedia -volumes 1-19. Propaedia Guide to the Britannica -1 volume. FIFTEENTH EDITION. Upon Hutchins's retirement in 1974, Adler succeeded him as chairman of the Board of Editors. Under the stewardship of Adler, Benton, and Charles E. Swanson (president of the company from 1967 to 1985), a vast editorial effort was assembled, resulting in the first publication of Britannica 3, or the 15th edition, in 1974. The new set consisted of 28 volumes in three parts serving different functions: the Micropædia: Ready Reference and Index, Macropædia: Knowledge in Depth, and Propædia: Outline of Knowledge. The articles in the Micropædia tended to be short, specific, and unsigned and were followed (until 1985) by index references to related content elsewhere in the set. The Micropædia also included brief summaries of the longer, broader Macropædia articles. The Propædia provided a topical guide to the encyclopaedia as well as information about the contributors. The 15th edition was given a global perspective by more than 4,000 contributing authors from more than 100 countries. The editorial creation of the work cost $32 million exclusive of printing costs, representing the largest single private investment in publishing history up to that time. Britannica 3's general editor was Warren E. Preece, and the executive editor was Philip W. Goetz. ASK OUR BOOKSTORE FOR SHIPPING OPTIONS OR ANY OTHER CONSIDERATION (pictures, condition, etc.)
