Traditionally, public libraries provide services to public without fee, because one of their missions is to provide free access to information. Today, that mission seems imperiled. Many people insist that information is a valuable commodity, and users must pay for its fare use. The purpose of this paper is to raise the issue of the information commodity and its effects on public libraries. Also, by the discussion of the functions and roles of public libraries, this paper intends to help public libraries in deciding their fee or free policy making.
