Library Journal is a trade publication for librarians. It was founded in 1876 by Melvil Dewey (familiar as the inventor of the Dewey decimal system). It reports news about the library world, emphasizing public libraries, and offers feature articles about aspects of professional practice. It also reviews library-related materials and equipment.
Its "Library Journal Book Review" does prepublication reviews of several hundred popular and academic books each month.
Library Journal has the highest circulation of any librarianship journal, according to Ulrich's — approximately 100,000.
