Bicentennial facsimile edition of the original Encyclopedia Britannica (1771), 3 vols. These are big heavy books bound in chocolate leatherette with gilt lettering on the spine and paper foxing retained. A winning combination of superannuated data and authoritative heft. I picked them up for a tenth their value at a Seattle Public Library book sale a number of years ago. Includes fold-out charts and tables and over 150 copperplates by Andrew Bell, who at four-foot-six rode the tallest horse in Edinburgh (with a ladder to reach the saddle) and got in bad odor with George III for his anatomically correct illustrations in the Midwifery article.
