The library research clearinghouse, already established by the american library association, was expanded to develop the requirements of a system of retrieval and dissemination of information about research in progress in library science. The basic objectives were--(1) to create the clearinghouses's services in acquisition, storage, retrieval, and dissemination of research information, (2) to assist in the development of a thesaurus of terms for the materials, and (3) to test and evaluate the effectiveness of the clearinghouse. Information about on-going projects was gathered through a previously established network, indexed, abstracted, and used in response to requests about current research. Requirements found for an information system of this type were--(1) development of a strong acquisitions network, (2) development of several criteria for input, including content, applicability, and date of publication, (3) development of a thesaurus, (4) establishment of a publication, and (5) development of a dissemination network. Of these, the development of criteria for input for the system determines to the greatest extent its effectiveness. (Author/cm).
