Second printing copy of Thomas S. Kuhn's The Copernican Revolution. Dust jacket has a fair amount of wear, wrinkling, creasing, scuffing and some chipping on and around the spine. Boards have some slight discoloration on the spine and tops of the boards, and the corners have bumping. The interior is mostly clean, save for a handful of pages that have underlining, and some remainder marks on the FFEP. An interesting look at the history of astronomy.
