The Clearinghouse on Educational Management produces information analysis products because the educational data base is so extensive and its quality varies considerably from document to document. Some of the Clearinghouse's products summarize and condense into manageable quantities the aggregate knowledge that exists. A second group of products makes judgments about what is of value and what is not. A third group interprets for school practitioners the implications of research findings for the operation of the schools. The products that compact the literature are primarily variations on the bibliographic format. The evaluative products are primarily state-of-the-art papers produced by experts commissioned by the Clearinghouse. The interpretive products usually both analyze and synthesize the literature. A good example of this group is the School Leadership Digest, a series of monthly reports that provide interpretive summaries of the research knowledge. (Author/IRT)
