Project SEIC (State Educational Information Center) was funded to increase the demand for and use of educational information, especially ERIC (Educational Resources Information Center) information, and to make more cost effective the delivery of information services. To accomplish these goals, Project SEIC first assessed the state-of-the-art of computer technology and then developed systematic programs of information dissemination/diffusion known as RSVP (Responsive Services for a Variety of Practitioners) and SID (Searches-In-Depth). This third volume of the three volume report contains the analysis of the statewide practitioner evaluation of comprehensive information services, including RSVP and SID. Included are (1) a description of the services evaluated, (2) a framework for interpreting the data provided in the appendixes, (3) a summary of the major findings, and (4) a statement of conclusions together with recommendations for further improvements in the service.
