A fairly extensive collection of letters, articles, extracts from notebooks of Leo Stein who is certainly- generally speaking-an unfamiliar figure. Introduced by Mabel Weeks who believes that his work was more significant than his sister Gertude's and will outlive hers once ""time has weakened the impress"" of her personality, Leo Stein was highly neurotic, introverted, unintegrated, for years lived in the self-bound world of psycho-analysis. The letters here reflect his interest in the world of inner experience; they also reflect his intellectual pursuits-writing, painting, reading; his health fads; his break with Gertrude and his contempt for her autobiography- ""that farrago of clever anecdote, stupid brag, and general bosh""; his love through the years for Nina which fluctuated in intensity until it culminated in a marriage of later years; the progress of his writing; etc. etc. A part of that eccentric, esoteric world which included Lawrence, Mabel Dodge Luhan, Maurice Sterne, Stein's name and audience is a limited one.
