This is a selective listing of organizations that promote books and reading, administer literacy projects, and encourage the study of books. Expanding on a brief list of organizations in the 1984 Library of Congress report, Books in Our Future, it focuses on national programs of special interest to the Center for the Book in the Library of Congress. The emphasis is on organizations in the United States, where recently there has been renewed interest in educational reform, in literacy, and in the future of the book. Alphabetically arranged, the entries provide addresses, telephone numbers, and contact persons for the organizations; general descriptions of their purposes; examples of their activities; the names of their publications; and a description of how they are funded. This information is based largely on materials that were provided by the organizations and programs themselves. Shared areas of interest include reading skills (the problem of illiteracy) and reading motivation (the problem of aliteracy); the state of the book industry; books and technology; the potential complementarity of books and the media; censorship; the history of books; and the international role of the book. Publishers, booksellers, librarians, book researchers, scholars, teachers, and writers are among those represented in this directory by a selective listing of their professional associations. An introduction by John Y. Cole entitled "Is There a Community of the Book?" opens the directory. (THC)
