You can download the History of Cartography from the University of Chicago Press, vols. 1-4 and 6 (a total of 8 books).
The project is nearing completion after 40 years (volume 5 is still in preparation).
You do have to download the pdfs by chapter (about 200 total) but do you have anything better to do today?
