This update of a 1977 training manual is designed for use by student assistants in the government documents section of John Grant Crabbe Library at Eastern Kentucky University. A brief introduction is followed by: (1) floor plans of the library; (2) a description of the documents collection including types of works and classification systems; (3) explanations of the major indexes and finding tools; (4) information on the policies for the circulation of materials; (5) explanations of the statistics on public service functions that are collected on a daily basis; (6) policies directly related to student workers; and (7) a discussion of the responsibilities of the student assistants. Three appendixes include a glossary; a list of abbreviations; and a list of letter designations for federal agencies and commissions. (CGD)
