Descendants of Cornelis Aertsen Van Schaick

I am fortunate enough to have all three volumes of Descendants of Cornelis Aertsen Van Schaick by Melwood Van Scoyoc.I am aware that someone (Sean Bagby and perhaps others) has entered the data into the format used by Geneology.COM.Does anyone know where I can obtain this information in GEDCOM format or some other format that can be imported into a genealogy program, such as Family Tree Maker?
Thank You.
