The complete text is now available online of Benjamin Franklin's reprint of James Anderson's Constitutions of 1723. This was the first Masonic book known to have been published in the American colonies, printed in Philadelphia in 1734.
Thanks to the National Heritage Museum's blog for the heads up. The Museum, owned by the Scottish Rite Northern Jurisdiction in Lexington, Massachusetts, has an original copy of the book. And, of course, thanks to the University of Nebraska for making the book available online.
