These guidelines are designed for use by persons working with the mentally retarded. They very briefly suggest how to deal with the library: discuss what you intend to do with the librarian, what privileges to request for the retarded, and what to do before going to the library. Several suggestions on what to do at the library are given and follow-up activities in the form of a library club discussion group are recommended. The goal is for the mentally retarded to be able to regularly use the public library successfully by themselves. (SJ)
