Folders organized alphabetically by topic of lectures given by Harold Varmus at UCSF in the virology and microbiology series and at Stanford University's Program in Cancer Biology. "A Seminar on Genetic Engineering" was offered under Microbiology 100A. One of his contributions was to create and supervise a program of intensive small group instruction in microbiology. Background materials range from 1967 through 1993. As well as lecture notes and syllabi, files contain annotated reprints, articles and letters to the editor from scientific and popular journals, clippings, generic case histories, lists of references and supplementary readings, and course outlines from other professors such as J.
