The Mark Twain Library Book Fair is the oldest – and one of the largest – in New England. The Library was founded by Mark Twain, himself in 1908. Today, more than 100 years later, the Book Fair is still one of the Library’s principal fundraisers. Labor Day Weekend – Sept. 2-5. This year – the wider aisles and a larger tent to accommodate for social distancing are back plus a more extensive online store! Over 65,000 books (and more) for sale in 75 categories. Highlights: vintage science fiction books, CDs in all music categories, cookbooks, books from the estate of Former Wilton First Selectman, classic children’s books, sheet music and an extensive Civil War section. FREE admission.
