I’ve been interested in collecting woods for a long time. The International Wood Collectors Society is the premier collectors organization, and they promulgate a “standard sample block” measuring 6″ x 3″ x 1/2″. The smaller IWCS-size samples are much cheaper than these wooden “books” offered by Worlds Wood Library, but there’s no denying the elegance of this idea as a display. The common name is cut into the book’s “spine,” and the latin binomial into its “cover.”
