An informal reading inventory (IRI), a nonstandardized individual test often constructed by the classroom teacher, can help teachers and clinicians in giving students appropriate reading materials and in diagnosing the strategies students use in reading. This annotated bibliography was designed to aid beginning teachers, as well as more experienced teachers. Entries are listed under the following categories: basic information on IRIs--history and critique, overview, and guidelines for contruction and use; dilemmas with IRIs--descriptive reports and research reports; comparing IRIs and standardized tests; psycholinguistic insights into reading errors; and related factors. Lists of unpublished materials (master's theses and doctoral dissertations) and of published reading inventories are also included. (JM)
