So you think you want to sell your rare books? Making such a decision can be exciting, but it can also be pretty intimidating. Should you try to sell the books on your own? Should you take them to an auction house? Or should you find a rare book dealer who can list them on consignment or buy them from you outright for resale? And how do you know how much the books are even worth? You may need to have your books appraised in order to know exactly what you have. Once you have a general sense of what your books are worth, you have a few options when it comes to selling them.
