I am using my own KISS (Keep It Simple Stupid) scanner, which
I designed myself. I originally called it a Tower Scanner, but
changed the name when I realized that I had made it as simple
as possible.
I posted a description of it on DIY Book Scanner, at:
https://diybookscanner.org/forum/viewtopic.php?p=22274&hilit=tower+scanner#p22274
As you can see I have a mirror in the base of the scanner
that I used to verify that the page is correctly placed. It
doesn't zoom in to fit the page, it just overscans.
If the USB i/f worked, you wouldn't need the mirror (?)

Your approach seems more like the Reading Machine used
(in "paper handling") -- though it used a moving camera-illuminator
to scan the actual page (which meant the book had to remain in place for
a considerable length of time):

>I don't do much manipulation of the images before I OCR them.>
I use Abby Finereader 14 which does a pretty good job of
picking out the text. I stick with 14 because it works good
and newer versions are only available as subscriptions.
All OCR tools "have problems". My scanner will do OCR but then I
lose the original images (so how do I sort out what the OCR *should* have
been once the original is gone?). I've also had some luck with
Omnipage.

The PDF doesn't have to get the text correct; it can store the
image of the page (and let your eyes/brain do the OCR).

I can store the OCRed text "behind" the image so that you can select
the text with your cursor (in a PC application). But, again, you
are stuck relying on the quality of the OCR algorithm.

As my goal is to be rid of dead trees, I have no choice in the
matter. Even discarding (scanning) all of my "paperbacks" leaves me
with a few hundred cubic feet of paper.

books on paper. After all that is how I grew up.
Agreed. But, if you are proactively safeguarding your collection against
the possibility of downsizing into a different living situation, you've
already decided that they will be discarded -- even if not "destroyed".
