I have been collecting rare books for many years, and The Philadelphia Rare Books And Manuscripts CO (Prb&M), LLC is one of the best sources I've come across. Their selection is unparalleled, and their staff is incredibly knowledgeable. The website is user-friendly, and the checkout process is seamless. I highly recommend this company to anyone interested in adding rare books to their collection.
