We Buy Old and Rare Books
Our speciality is in old and rare books, specifically early printed books before 1800 including incunabula, early Bibles (pre-1800), manuscripts in general, handwritten books, medieval manuscripts, books of hours, archives, natural history books, color plate books, books on travel and exploration and much more. If you can provide quality photos of the book(s) binding and title page with date, we are often able to make offers based on those.
