Members of the Research and Development Exchange agreed to collaborate in the development of a resource base on the identification and validation of promising educational programs, practices, and products. Part of that effort has been the development of a central file of resource materials on validation and the abstracting and indexing of those materials. The 89 publications annotated here are in the resource file collected by the Research and Development Interpretation Service for the collaborative effort. Accession number, title, availability, abstract, and descriptors are provided. An index following the bibliography assigns the documents to major categories. (Author/MLF)
