David, I wouldn't worry too much about it. Based on these discussions, I actually feel that maybe I'm overemphasizing the historical value of these books. As Adam says, they are not priceless illuminated books, and on the other end of the spectrum they aren't modern magazines. They are somewhere in-between. Perhaps the best you can do, if it's important to you, is to build your own library of original books. They haven't gone up in price over the last ten years, despite the cut-outs, so it's possible that there are so many of them available that we have an endless supply
