Books can be a great source of fun and delight, both for the stories they tell, and also in their objectual selves, as collecting books, whether it is signed copies, first editions or antique books, it is a very important (in terms of number and value) and widespread hobby. To give credit to my words is this site, the official home of the Antiquarian Booksellers Association of America, where visitors will be able to learn about this organization of professional antiquarian booksellers, their history, activities, events, fairs, plus view highlighted books for sale by some of the affiliated booksellers, a list of which can be found at the site, which will come in very handy for skeptical buyers.
If you are looking for a specific book you can’t find, consider visiting this site to use their search engine, which looks in the inventories of all its members, some of which probably don’t sell in eBay or Amazon, so this is a good way to get hold of much searched-for material. If you are a fund-less book lover, you can still profit from this site by browsing the catalogues of the booksellers, which presents lots of additional information, so you can still get to learn something in the process as well. If you have a book to sell, mind that you won’t be able to sell it to the association itself, but you can still search for affiliate antique booksellers in your area, who can get an appraisal for your goodies.
