New York Biographical Dictionary: People of all Times and All Places Who Have Been Important to the History and Life of the State, published by the American Historical Publications (HC, 1986, 596 pages, $15, which is 1/3 the internet price)
This a beautiful book, with a wonderful quality of paper. (Translation- Isn't this paper really thick and white!) It may be ex-lib, but the only clues are tape mark residue on the binding, and "Plattsburgh Central" stamped on the copyright page. There are a few underlingings.
I don't think much of this book. How can you have a long section on Alan Alda, and not have anything on Nathaniel Rochester? It would seem that all the people included were born in New York, and Rochester wasn't. Still, the title reads people who have "Been Important to the History and Life of the State", a category that Col. Rochester certainly falls into.
As long as it doesn't matter to you that Rochester isn't mentioned, then this is quite a book. Look for it in the local section, avail. 1/11.
