There used to be a scanner - I have long since forgotten the name - that

couple of lights also, of course. I'd imagine that such a unit would be
capable of scanning magazine pages with out ruining the magazine. I
also imagine that it was bog slow and low resolution!

I've found that hanging one edge of the
magazine over the side of the
scanner works - you have to put the scanner on something thin and tall, so
the whole side of the magazine droops down - the only problem then is the
width of the plastic edges of the scanner surface/sides of scanner
I once disassembled my scanner to investigate the
possibility of removing the entire "plastic edges
of the scanner" all the way to the edge of the
scan area.(Hoping to be able to scan old books
only open to a 90 degree angle.)
It looked like a good idea because the outside
track is inside the scan area. Unfortunately
after I got the scanner apart, I discovered that
the xenon(or whatever) tube not only does not light
all the way to it's end, but it also has an
electrode at the end. It just sticks out too far
and has to extend past the edge of the scan area
in order to illuminate the whole area.
Oh well.
On a similar note:
I just found this - "Building a megapixel digital
camera from a flatbed scanner"
