Neugebauer Microform Index of the Exact Sciences

"The Institute for Research in Classical Philosophy and Science (Princeton) currently has under its care the 26,002 file-cards prepared over 60 years by Otto Neugebauer (1899–1990), the renowned historian of the exact sciences. On these cards are written by hand the very detailed and meticulous notes which Neugebauer has used for research and publication throughout his career. These cards fall into two types. The first are subject-cards which divide the history of the exact sciences by time period, culture (Classical Greek and Roman, Babylonian, Egyptian, Islamic, Judaic, Byzantine, European) and topic (the various branches of the mathematical sciences such as arithmetic, geometry, trigonometry, astronomy; scientific instruments, calendars, lexica, and so on). These subject-cards are keyed to the second type of cards, the bibliographical cards which record the literature and documents that Neugebauer consulted.With the permission of Professor Neugebauer, the Institute for Research in Classical Philosophy and Science has prepared microfilm and digital versions of these cards which will now be made available for research purposes only to scholars and institutions, along with a user's guide and directory."
