in 1918 the Joint Executive Com mittee of the Vocational Education Committees of the Pulp and P a p e r Industry. This was a group of TJ. S. and Canadian industry men who in 1921 published the standard indus t r y work entitled " P u l p and P a p e r Manufacture." The current fourvolume edition of this work, p u b lished 1950-53 by the McGraw-Hill Book Co., remains the most exten sive text on the subject today. P a p e r m a k i n g bibliographies were prepared by the T A P P I Bibliog raphy Committee, starting in 1915, and have appeared annually ever since. In 1939 the first T A P P I D a t a Sheets, largely concerned with pulp and paper mill engineering, were issued, and there are now 202 in print. T A P P I Special Reports on manufacturing problems were first issued in 1923 and have a p peared every year to date, with a total of 426 issued. I n 1942, the first of 20 T A P P I monographs on papermaking a p peared. I t was entitled "Industrial W a t e r for Pulp, P a p e r and P a p e r board Manufacturing." These are prepared by the technical commit tees as the need is felt. I n J a n u a r y 1949, the first issue of the association magazine, Tappi, appeared. Previously, papers pre sented at T A P P I meetings were published as Technical Association Papers and in a special section of Paper Trade Journal. T h a t first year Tappi published 1540 pages and in 1958 published 3398. The text-advertising ratio is two to one.

In 1929, when association mem bership stood at 1033, the first local group was chartered—the Pacific Coast Section. Today, there are 23 groups located in and around the leading papermaking sections of the United States and Italy. A E u r o pean T A P P I Study Group is also in existence, this being an interna tional effort on the part of E u r o pean members meeting once a year for the exchange of ideas. All these area organizations serve as a point of contact between T A P P I mem bers and nonmembers and are con cerned with technical problems pe culiar to an area. Some are inter ested particularly in pulping and papermaking, others in converting. They all have the nature of forums. From the beginning the real work of the Technical Association has been carried on by its standing committees. The development of this committee organization has been one of normal growth. Where an area of the industry could be served by a T A P P I committee, such was organized. Today, 61 commit tees are working in eight divisions concerned with engineering, pulp manufacture, paper and board manufacture, testing, coating and graphic arts, converting, corrugated containers, and research and devel opment. T h e Testing Division is composed of 17 committees and, with the Standards and Routine Control Methods Committees, is responsible for T A P P I test proce dures.
