This volume consists of notes, themes, and sketches for works which Anton Chekhov intended to write, and are characteristic of the methods of his artistic production. Among his papers was found a series of sheets in a special cover with the inscription: "Themes, thoughts, notes, and fragments." Madame L. O. Knipper-Chekhov, Chekhov's wife, also possesses his note-book, in which he entered separate themes for his future work, quotations which he liked, etc. If he used any material, he used to strike it out in the note-book. The significance which Chekhov attributed to this material may be judged from the fact that he recopied most of it into a special copy book.
