I was doing a literature search in Google Books

I had decided to look in Google Books to see what was currently available for 17th Century naval history and naval history generally. What had gotten my attention is that several books are available that I had not expected to find, such as the biography of Richard Badiley, among others. After I had downloaded 33 volumes, Google Books freaked out and blocked any further searches, as they were concerned that this was an automated search and download. I suppose that was because I was so consistently on topic.
