Gitlitz & Davidson Book or other books electronically?

[Rambler]

I am trying to see if I can lighten my load a bit by finding any of the guidebooks, or especially the Gitlitz and Davidson book electronically, so I can have it loaded on my phone and not have to carry the paper copy.
Does anyone know if these books are available electronically or where to find out?
Thanks.

Fast forward to 2013-- I have the whole book on my 6 inch (2 oz) tablet! Priceless!
