Public Libraries Public libraries generally feature convenient locations and fewer restrictions on borrowers. Because public libraries serve a more diverse community than other library types, public library collections give general coverage to many topics and in-depth attention to few. Most public libraries have basic reference books, standard or classic works on most topics and general periodical indexes. Few public libraries will offer the in-depth, or professional, or scholarly materials necessary to complete all the courses of a graduate program. These collections may not be large, but they give excellent coverage of their specialty.
Many communities are home to public or government agency libraries.
A few examples would be a law library in a public courthouse, or the U.S. Geological Survey Library. In addition, private corporations, such as IBM or U.S. West, also have collections pertaining to their special interests. If the researcher is employed by a corporation or agency, he or she may have access to the firm's library and may also have other privileges such as online searching. If the researcher is not connected with the agency, it is advisable to check in advance. School Libraries Libraries in elementary and secondary schools are usually geared to the needs and levels of their students.
