The Lyrical Ballad in Saratoga, NY, is one of my old favorites. It was founded over 50 years ago and located in the basement of a building that used to be a bank. You’ll find room after room just filled to the brim with used books, antiquarian books and periodicals, and prints. It even has the original bank vault with brass cage doors and books inside. I’ve shopped there for over 30 years, whenever I find myself in upstate NY. The original owner, John (now deceased), once told me he had twice again as many books in storage.
