During his long mathematical career, Dan Quillen, Waynflete Professor of Pure Mathematics in Oxford from 1984-2006, kept a set of detailed notes which give a day-to-day record of his mathematical research. His notebooks have been digitised in a project funded by the Clay Mathematics Institute (CMI) and made available to the mathematics community on the CMI website. Glenys Luke and Graeme Segal are working on cataloguing the material. So far, the work has been completed up to the end of 1977.
