Rick (and Listers) The General Society of Mayflower Descendants has spent a vast number of years and an enourmous amount of money to make these "Silver Books," etc., available to people who are doing research on the Mayflower Families and applying for membership. It is very unlikely that you will ever find them in anything other than book form, until the copyright runs out (and cannot be renewed) and/or the Society has recouped its monetary expenditure.
