In folding printed sheets for sewing into bookbinders' signatures, every other pair of pages evolve from one side of the printed sheet of paper. Thus, if color is printed on only one side, a reader finds color on every other pair of pages in the book. In this way it is possible for the reader of this book to judge the effect of color on the varied types of charts shown in the 60 chapters simply by turning the pages two at a time. It is believed the evidence is conclusive that to get maximum results in graphic presentation the question is not "Can one afford to use color?" but "Can one afford to omit color.?"

This book Graphic Presentation results from the work of many people. It would not have been possible except for the charts produced by the individuals and organizations to whom credit is given under many of the 676 illustrations. The illustrations were selected from thousands of clippings

PREFACE

which I could not resist saving during the 25 years that have elapsed since publication of Graphic Methods for Presenting Facts in 1914.

The chapter on selection of paper was prepared by Mr. W. B. Gibson, of the Mead Sales Corporation, in consultation with officers of various trade associations. My wife, Laura M. Brinton, did practically all the work in preparation of Chapter 46, "The Camera and Its Use"; Chapter 47, "Lantern Slides," and Chapter 49, "Color and Its Use." Miss Audrey W. Zeigler, of Newburgh. New York, made all the drawings used as the headings of chapters. Mr. R. R. Lutz, of the National Industrial Conference Board, made valuable suggestions in the early stages of planning the book, particularly regarding the possibilities for the use of color. Mr. Roy S. McElwee, and numerous others read manuscript and contributed suggestions as the book progressed.
