John C:
I don't know optics as well as I probably should, but I wonder if the polarizing filter might be either overkill or potentially counterproductive, depending on the kind of lighting (I very vaguely remember reading that some LED lights are strongly polarized, but I can't recall where I heard it, so that may well be wrong).  A diffuser for the light source (on a dimmer) might solve the same problem in a more global way.

The trick the DIYers seem to use is to have a v-shaped glass rig to insert between the pages at a right angle.  That keeps the overhead light at 45 degrees and keeps both pages available to be shot.

The dark room is a really good (obvious now that someone's said it) point.
