This guide, which gives student library assistants background information about the New Mexico Tech Library as a whole, is designed to be used in conjunction with the operations manual of the department in which the assistant is placed. It provides information under four headings: (1) Library Departments (reference, interlibrary loan, technical services, circulation, periodicals, archives, acquisitions, and audiovisual equipment); (2) Non-Library Departments (the curriculum collection, tutoring services, and the typing room); (3) Work Skills (general student employee information and suggestions for good telephone and business etiquette); and (4) Library Specific Skills (who is responsible for answering reference and directional questions, servicing photocopy machines, and getting supplies). Discussions of the library's classification system and emergency procedures are also provided as well as floor plans of the library. (KRN)
