The last of three library skills modules for college students, Unit III provides definitions of periodicals, indexes and abstracts, as well as discussion of how to select the appropriate index or abstract, how to interpret a citation, and how to locate bound journals, microfilms, and current issues of journals in the library. Copying and borrowing regulations for magazines are explained. How to use newspapers and their indexes is the topic of the concluding exercise. Included with the unit are six tests which are used to evaluate student achievement after completion of the module. (JAB)
