On a bookshelf in the Bertrand Russell Research Centre is a set of blue, hardbound volumes, all well-thumbed. These volumes, twenty-two and counting, reflect many years of researchers’ time and sweat, and constitute a sizeable portion of The Collected Papers of Bertrand Russell. This critical edition of all Russell’s unpublished books and his shorter writings, published and unpublished, is projected to be completed in 35 volumes plus the three-volume Bibliography.
