This supplementary report was designed to aid the researcher concerned with concept learning. It contains: (1) rationale and strategy for compiling a bibliography of articles concerned with concept learning; (2) a definition of the world "concept"; (3) a system for classifying articles by their content; (4) a bibliography of relevant articles arranged alphabetically by author; and (5) a bibliography of the articles arranged according to their content. The first step in compiling this bibliography was to systematically and comprehensively search fifty selected journals and publications. The text of each article in all issues was examined to determine whether the article met criteria established for inclusion in the bibliography. The primary specified criterion was that the article include the terms concept, concept formation, concept identification, concept attainment, or conceptual learning in either: (1) the title; (2) a subheading; (3) an abstract of the article; or (4) the summary or conclusion.
