I found a review (which I uploaded to my Box.net account) published in 1912 of the books Ireland Under the Normans (4 volumes) by Goddard Henry Orpen. Mr. Orpen's books were published in 1911 and can be found at Internet Archive, a positively awesome source for public domain books. In any case, the review inspired me to read Mr. Orpen's books, but they will have to go into the list of "Books I Need to Read". If anyone has read these books and would care to comment, I would appreciate if they are actually worth reading after all. :D
For a glimpse into how and what he writes, Mr. Orpen also wrote "The Effects of Norman Rule in Ireland, 1169-1333", which I have, you guessed it, uploaded to my Box.net account. Happy reading!
