The years covered in this report (1979-81) have been active ones in the field of stellar classification, as is made obvious in the following sections. In addition to the individual references listed there, a number of symposia, colloquia, and workshops were held during the report period which included papers relevant to stellar classification. These include IAU Symposia 85 (Starclusters), 98 (Be stars), and 99 (Wolf-Rayet stars); IAU Colloquia 64 (Automated Data Retrieval in Astronomy) and 68 (Astrophysical Parameters for Globular Clusters); and the Dudley Observatory Workshop on Problems of Calibration of Multicolor Photometric Systems (1979).
