This guide provides an introduction to library and information science resources available at the Library of Congress and on the Web. Its intended audience is librarians, library technicians, and library science students. Special emphasis is given to freely available online resources that can be used by librarians and library science students without ready access to print resources and subscription databases.

The guide's Frequently Asked Questions page provides answers to a number of the most common library and information science questions, and questions in related fields, received by the Library of Congress through its Ask a Librarian service.
