Hi to you all,
I found a website that sells family history books and what makes it unique is that with each book comes a free searchable CD, no other site offer this kind of deal.
They have those books that I have been searching for a long time.

The Wyckoff Family in America: A Genealogy - by Waiting for Order Summit, NJ , 1950
The Wyckoff Family in America: The Nicholas Line (Watsonville, California Branch): A Genealogy - by Wyckoff, Hubert Coke n/a , 1965
Check it out, it is worth it.
