As the growth of eBooks and database formats accelerates, selecting reference materials for school library collections has become a complicated process. Like previous editions, Guide to Reference Materials for School Library Media Centers, Sixth Edition is designed to suggest the best material in all formats, on all subjects, and at all levels—to help school librarians find the best resources.

To compile this guide, the author reviewed materials in school, public, and community college collections, and confirmed quality by examining published reviews in standard library reviewing guides. The resulting book lists reference tools for school librarians and has major sections recommending general science, humanities, and social science reference books, eBooks, and subscription databases for K-12 library collections. Materials listed come both from publishers who specialize in K-12 materials and publishers whose market is not typically school libraries.
