Mississippian Jim Henson's puppets Kermit the Frog and Miss Piggy are featured on a new poster produced to promote the campaign "Building a Nation of Readers" of the Center for the Book at the Library of Congress. The Center for the Book was established in 1977 to stimulate public interest in books, reading, and libraries and to encourage the study of the role of books and print culture. John Y. Cole, director of the Center, said the theme of the poster "emphasizes the importance of reading to our democratic way of life." The production of the poster coincides with plans of the Library of Congress for celebrating its bicentennial in the year 2000. The 22-by-34 inch poster is available for $9 in the Library of Congress Sales Shop and by mail from the American Library Association, phone 800-545-2433. Bookmarks are also available at a cost of $6 for a pack of 100.
