Series II, WRITINGS, is divided into unpublished and published work. Among the unpublished materials are articles dealing with evolution, ecology and other scientific subjects; drafts and outlines for chapters of The Living Whole; memoranda, prepared during Shepard's years in government service (1943-1950); and notes on various subjects including energy, evolution, nature, philosophy, psychology, science and teleology. The final section of unpublished material contains a number of unidentified and undated papers on a variety of topics. These appear to be proposed articles or addresses written by Shepard after his retirement. The published material consists of reprints of articles and book reviews published by Shepard in various scientific magazines. The series is arranged in five sections; articles; books; memoranda; notes; typescripts. There is one section of published reprints and reviews following the unpublished materials. Within each section items are organized chronologically, followed by the undated materials, which are arranged alphabetically by title.
