Eight documents of representative types and three journal articles are included in this self-instructional training workbook for abstractor/indexers. Introductory materials provide an overview of informative and indicative abstracting styles and the principles of indexing utilized by the Educational Resources Information Center (ERIC). Detailed step-by-step instructions are given on examining documents, abstracting, and indexing. The first two documents, a state-of-the-art review and an opinion paper, provide practice in the informative abstracting style. A program development guide, a curriculum guide with instructional materials, and a collection of essays represent indicative exercises. A research report deals with the mixed abstract mode (i.e., informative/indicative). A second research report and a document of composite focus provide experience with author abstracts. Journal article exercises emphasize the synthesis of extensive information. Each exercise includes an analysis of requirements, practical strategies, and alternative approaches to handling the document. Suggestions to supervisors for using the "Workbook," sample worksheets, a list of "do's" and "don't's," and a list of verbs are also provided. The workbook is intended for use along with the "ERIC Processing Manual," the "Thesaurus of ERIC Descriptors," and the "Identifier Authority List." (BB)
