Since I started it, maybe I should end it. This is not really a "sale." It's a periodic lower price. Wait three or four months, and Higginson Books will put it in their ad again at this same price. But, if you order it next month, the price will be quite a bit higher. Just wanted anyone interested right now to know that they should avail themselves or plan to wait some months. In each of their ads, they feature certain of their books as a lower price. This cycles around among the most popular titles. This is the 1953 Knapp Genealogy, no supplement as far as I know. If you order now, it might come in time for Christmas. Hope this answers all the questions. Tom Cornell
