These two brief guides are designed to assist users in searching the GPO Monthly Catalog of Government Publications and the ERIC databases on CD-ROM produced by Silver Platter Information, Inc. Each guide contains step-by-step instructions for: (1) simple subject searching using basic Boolean connectors; (2) displaying and printing; (3) correcting typing errors, stopping printing, and using special keys; (4) title, author, descriptor subject, and index searching; (5) interpreting search results; and (6) selecting show and print options. The guides were prepared at Appalachian State University for use with college students and library staff. (KRN)
