The document discusses how book covers influence student choices in school libraries, with surveys finding that covers are the top factor in fiction selection for both boys and girls. While the idiom "don't judge a book by its cover" is meant to advise looking beyond appearances, students often judge books primarily by their covers. The document suggests strategies for librarians to promote books with less attractive covers, such as through book talks, displays, contests, and viewing the library space like a bookstore with attractive merchandising. Librarians are encouraged to educate students about how covers are marketing tools rather than reflective of a book's quality and to advocate looking beyond the cover.
