Ross, I am putting together a PDF for the Heritage Auction texts (with David Akers commentaries) for many of the most famous, most-expensive Saint-Gaudens coins sold on their website. I think I have one for every year from 1907-32, and am finalizing the layout.
Basically, I wanted something on my smarpthone and wanted the David Akers commentaries from the 2012 Duckor FUN catalog as well as some comments from 2008 and 1988...in PDF form. Some of the commentaries are short (1 or 2 paragraphs) and others like for the 1907 UHR or 1907 HR, or for rarities like the 1929-32 batch, are a few pages each.
It's not Roger's book or even the Akers 1907-33 Gold Handbook or Bowers' Guide Book on Double Eagles...but it does have lots of Saint information (at least on the finest coins)....is in PDF format....and has lots of catalog commentaries (from Akers) which can be read on your smartphone.
If interested, let me know.
