Between 1879 and 1895, M. A. Markham of Lakeville, New York, composed at least 21 volumes of illustrated problems and solutions for games of checkers. Checkers originally had 25 volumes, of which 21 are present: volumes 1-6, 9-14, 16-19, and 21-25. Volume 1 is divided between two books, and volumes 3-4 are written in the same book. Most individual volumes contain between 100 and 200 pages of illustrated problems and solutions, which Markham collected from a variety of sources, including newspaper columns. Pictures of game boards with pieces in various positions are grouped together, and solutions frequently appear several pages later, written in the game's notation. Each volume has an index. Many volumes are subdivided into several parts, and headings are decorated with colored ink drawings of landscapes and buildings. Clippings with engraved portraits and biographical information about famous checkers players are pasted opposite most volumes' title pages.
