The Special Library is distinguished from other libraries as being a library serving a particular group of readers, who have an existence as a group outside of their readership of the library, and whose members direct at least some of their activities towards a common purpose. Thus, the special librarian's first and major responsibility is to know just what are the purposes of the organization he serves. The special librarian must be more interested in giving information services than in collecting and preserving books for posterity. The bulk of this speech concerns the types of information services the special library should be able to give. The complete dependence on computers to produce these services is not recommended. The social and cultural fields are considered to offer the richest rewards for special librarians in developing countries. (Author/NH)
