Cover — a Sally Rosenbaum oil painting, reproduced at high resolution
Size — 5 x 8 in, softcover, fits a purse or bag
Interior — 200 pages with a table of contents at the front

Kept properly, a commonplace book becomes the most useful object you own: every quotation, address, sketch, and half-formed idea from the last five years, indexed and retrievable. Locke published the method in 1706. It asks only one thing of you — number the pages. The 5 x 8 size fits a bag without folding.
