Publications and Drafts This series is divided into two sub-series. The first contains copies of Haldane's published work and drafts of his publications. This is separate from his notes and rough drafts, which can be found under the series HALDANE/1 Scientific Research, although there is some overlap between his published work and notes. The second sub-series contains published works, primarily on scientific subjects, authored by people other than Haldane. This includes proof copies, offprints and copies presented to Haldane by the author. 20th Century
