If your looking for the eBay of genealogy publications, then find your way over to GenealogyClassifieds.com.
The place to find new, used, out of print and just plain hard to find Genealogy Books. If you have an old, used genealogy book or publication on your bookshelf and no longer use it then you can make some extra money and help another fellow researcher out by selling it here as well as putting some of the original cost you incurred back into your own pocket for new genealogical books or publications purchases. This site works something like eBay except we are geared only towards genealogy books and publications. One extra bonus is posting your items here is FREE. There is no cost to you to place an ad on Genealogy Classifieds, just your time and effort.
