Seeing this dredged up reminded me that I meant to try something, and since it's raining today...
I like quick and easy, and quick, easy, and cheap is even better. Here's what I did with a TV tray, a couple of lights, a throw pillow, a piece of plexiglass, a camera, and a tripod. The back leg of the tripod is longer than the two in front, so the 8 MP camera is pretty much directly over the book with a clear view.
The two halogens are clipped to a TV tray. The light on the left is aimed a little higher, to throw more light on the far side of the book. The light on the right throws more light on the near side of the book. Both lights light the middle.
The book sits on top of a throw pillow from the couch. On top of the book sits half a platen from a previous build; it's 1/4" plexiglass. The pages of the book are 9" x 6".
Here's a shot of a pair of pages:
And here's what it looks like after it's gone through Scan Tailor:
