SUMMARY Several conclusions may be drawn about the media of communication, book reading, and the public li- brary. It has been demonstrated that among the major public media of communication the book attracts the smallest audi- ence; that about one fourth of the adult population of this country reads one or more books per month; and that book readers tend to use other media of communication (with the exception of radio) more than do nonreaders of books. About one in ten adults and one in three children and young people are “real users” of the public library, that is, use it at least as often as once a month. Of the books read in the United States, the public library supplies about one- fourth.** Like book readers as a group, public library users tend to make more use “of other media of communication (again excepting radio) than do nonusers of libraries, and persons having book collec- tions in their homes use the public library more than do those without home libraries. As a source of information, the public library has little reality for most people. “SRC, 1948, p. 55. "As suggested earlier, there is no contradiction between the figures refer- ring to users and those referring to books supplied. The public library may provide about a quarter of the books read and yet reach more or fewer than a quarter of the readers because of the multiple and differential use of sources by the same people.
