Using the term technical to include scienctific libraries, this guide is designed to aid librarians who, without having a technical background, find themselves working in a small technical library. An overview is presented of the field of technical librarianship--professional associations, working environment, and the relationship of the library to the parent institution. Instructions are provided for the physical organization of the library, for the acquisition and processing of materials, and for information service to clients in the form of current awareness bulletins, translation, and bibliographies. A classified bibliography of further reading is appended. (SL)
