5.4 FOREWORD during the last decade, he is well equipped for such a task. When the results of the Berelson and Likert studies were laid side by side, it became apparent that they covered many of the same topics. More important was the discovery that data on use in one reinforced the data in the other so that together they formed a reliable pattern of approximations regarding library and book use in the United States today. The decision was made, therefore, to include the Michigan Survey Research Center findings as part of the inclusive review of all data on library use, to be presented in a single volume.

Reference in the following pages to the data in that report is indicated in all cases by the symbol SRC. What is presented here, then, is a synthesis of the studies of public library use made during the last two decades, including the national survey made especially for the Public Library Inquiry and employing the most reliable sampling techniques available to the profession. This is not to say that in the following pages the reader will find in the exact percentages complete or final answers regard- ing the use of the public library. Dr. Berelson points out care- fully in his Note on Method the limitations marked out by the available data: for example, that there is relatively little reliable evidence regarding the reference use of libraries and practically no evidence regarding the unrecorded use of li- braries by reference workers who find their material by them- selves, although the reference function of the library is a
