Results of a five-month exploration of potential objectives and structures for the Educational Resources Information Center (ERIC). The range of objectives considered are those appropriate for a total educational information system. Ten information-system objectives are defined, based on the relationship between overall system functions and user groups. Six models of potential ERIC system structure are presented, in order of increasingly comprehensive changes to the existing structure; and criteria by which to evaluate the various alternatives are suggested. General conclusions are reached concerning the need for evaluation and synthesis of the present database; deficiencies in current education literature; relative effectiveness of the suggested systems models; the need for expanded management responsibilities, skills, and funds; the need to improve the interface between ERIC and other information resources; and the need to make ERIC's products more useful for its intended audience. 93 pp. Bibliog.
