The Oliver Reiser Papers comprise a wide variety of materials dating from shortly after Reiser's completion of his Ph.D. to shortly before his death in 1974. Reiser's correspondence reflects his many intellectual interests and his commitment to interdisciplinarity. The publications series contains only a portion of his published work, but the annotated drafts and diagrams therein provide valuable insight into Reiser's writing and revision process. The Personal Papers series and Media series contain many materials unique to this collection, including Reiser's handwritten notes on disparate subjects, his thematically organized folders of scientific and philosophical literature and his awards and clippings. Key themes include the following: general semantics, the integration of knowledge, the history of philosophy, the philosophy of education, the philosophy of mind, world peace, and, world religion.
