This workbook in library skills designed to acquaint Pennsylvania State University students with the facilities and resources of their library is used in conjunction with courses offered at the University, and its mandatory completion is incorporated in the final course grade. It is organized into exercises dealing with types of materials rather than by area of the library. Each exercise has an introductory section explaining the material covered, followed by a set of questions to be answered individually by students. Specific areas covered include the card catalog, classification systems, periodical and book review indexes, dictionaries, encyclopedias, almanacs and statistical sources, biographies, newspapers and newspaper indexes, government documents, maps and atlases, audio services, the stacks, and the reserve reading room. Floor plans of the various areas of the library and examples of catalog cards and other forms are provided. (Author/MBR)
