The general editorial plan behind The Collected Papers of Bertrand Russell calls for two parallel series, one concerned with Russell's work on philosophy, logic and mathematics, the other with his less technical contributions in areas such as politics, practical ethics, history and education. Volume 1, sub-titled Cambridge Essays, 1888–99, is in a sense the ancestral volume of both series, for it comprises both technical and non-technical subjects. Russell appears here as diarist, public speaker, political commentator, as well as apprentice philosopher and expert on non-Euclidian geometries. The Collected Papers as a whole will span the more than 80 years of Russell's writings devoted to a formidable range of topics from the personal to the highly abstract but, large as it is, this publishing project will make no attempt to bring together the totality of his writings, since many of these remain in print and are readily available. Instead, the project's distinct emphasis will be on Russell's shorter writings, such as essays, articles, reviews and speeches, which are not so easily located, even when previously published. Grouped together in convenient subdivisions, these papers will chronicle for us Russell's intellectual and social growth to an extent even greater than that attempted by Russell himself in his three-volume Autobiography or in My Philosophical Development, and they will also serve to acquaint us with the thoughts, feelings and attitudes of the venerable figure behind the well-known major books. The project's essential aim, then, is to mine and refine the vast Russell Archives in a way that will yield a permanent foundation of study for anyone, whether mere admirer or life-long scholar, who has any interest in Russell's life and work.
