One score plus one year ago, to wit, July 4, 1946, Borrowdale, “the smallest bookshop in the world,” opened its doors to the public in Edgartown. It was then, and is still today, the only shop on the Vineyard devoted solely to the purveyance of literature without resort to the lure of coupons or kickapoo juice or the like. Established by the late Gerald and Margaret Chittenden shortly before his retirement from the faculty of St. Paul’s School, Concord, N.H., Borrowdale quickly became known as the place you could purchase good books immediately, and order the other kind.
