The subjects of his Cahiers entries often were, surprisingly, reflections on science and mathematics. In fact, arcane topics in these domains appear to have commanded far more of his considered attention than his celebrated poetry. The Cahiers also contain the first drafts of many aphorisms he later included in his books. To date, the Cahiers have been published in their entirety only as photostatic reproductions, and only since 1980 have they begun to receive scholarly scrutiny. The Cahiers have been translated into English in five volumes published by Peter Lang with the title Cahiers/Notebooks .

I have used this organizer for the last 3 years for both of my daughters. Each book is set up for one year's worth of pages. It serves as a fun visual guide for students and excellent goal maker for parents. Believe it or not, my daughters will do anything to earn those check marks and little stickers as a reward. You can get as creative as you want with the check boxes and stickers. Page is divided by categories (warm up, scales, techniques, repertoire, orchestra/quartet pieces) and this helps students/parents organize the practice for each day. Since whole week's worth is on one page, this helps us set a goal for each day and for each week as well. Check boxes serves as a visual incentive for students to see how much progress they are making and how hard they worked to get there. My girls and I enjoy using this organizer year after year and will probably continue to use them for many more years to come.
