Originally posted by philbaum I haven't read all the replies, but why can't you use a table type scanner to "photograph" the book pages. The glass is already there and they are relatively cheap.

the problem with a scanner is the distortion that happens where the pages curve toward the spine. It's usually pretty unattractive. If ya ever have copied something from a book on a copy machine you will have seen this in action.
Beyond that though, I have typed out a few replies to the OP but deleted them. The thing is I am not liking the sheet of "something" over the book to hold it and shooting through. It is going to be a real PITA to control reflections, including the camera rig which has to be positioned directly over the book. There are just too many factors that need to be managed for each and every book, meaning the ability to reproduce quality results one after the others might be very frustrating for the OP.
The reason I didn't post my comments was I am trying to word the solution I would try. Mostly it comes to this, if the OP wants to shot pages and layout samples then the odds are there exist copies of these books in electronic form somewhere...use those and just show the layout. To get shots of the whole book and have them flat, that is not going to be possible. But a creatively arranged selection of titles with one book held open with both a combo of
Scotch non-permanent double-stick tape (same kinda adhesive as used on post-it notes - no residue, no damage to the paper), a nice wooden or even metal plate holder/stand (I use some vinyl covered wire-frame plate stands all the time as I can bend them) all combined to create a nice arrangement of the books and using DOF to control emphasis would do the trick...but to do this right is a non-trivial task, especially as the OP indicated he has a lot of books to shoot as samples.
Last, 50mm is simply too long on a crop. I know, I tried it out and I have all the toys to make this work. Even 43mm is not wide enough if the books are above trade-paperback in size, if 8.5" x 11" then forget it unless the OP has the ability to crop thanks to a higher pixel count.
Here are some samples at 43mm:

Now those are not great examples nor I am using the tape mentioned but I did use some hidden plate stands, three daylight 30w daylight trumpet bulbs and a tripod. You can see there is still not really enough light. I like using books to decorate the shot might because books "like" to hang around with other books. If I had a wider lens, say 28mm or wider, then you could get closer to the subject book and increase the effectiveness of the DOF. But more light is needed for sure. My goal there was to show what I have been trying to describe. The lighting is still the key and I am not sure the results using the transparent sheet to flatten the books is the way to go as lighting is going to be even more critical and a wider lens will be imperative...I would say 35mm macro is the longest I would use...isn't there a close focus 28mm by Vivitar(?) out there somewhere? but I am willing to bet that would blow the OP's budget by a hundred bucks or so...
Also I would setup on a low table either way. That will allow for shots from directly above the books when it matters, though it could make angled shots somewhat tedious. No matter I see that one will need a lot of working room to do this right, I would say at least 5' across though I had 4' and it was workable. To get these shots right'er I think would require me to setup at least 3 additional lights or use a couple off camera flashes. But the OP would need to buy flashes, and buying a few more lights would be much cheaper.
The final trick I would use to help flatten the books would be to leave them open face down opened to the page I wanted to show-off. I weight on the book would help flatten them and I would bet you would need to leave them that way over night. Also this idea runs the risk of damaging the spine as binding, it's a trade-off in order to get the shot.
