Presented is a second supplement to previous lists of references. This document is a compilation of information collected by the Calculator Information Center between December 1980 and March 1982. Included are references which previously appeared on bulletins distributed by the center, plus articles from newsletters and similar less readily available sources and from non-American sources. Most references are annotated; all include a limited set of descriptors or keywords which denote the focus or contents of the reference. At the end of the listing is an index for each descriptor. (MP)
