Alan,
Ever notice in libraries, how all the books (mostly anyway) are shelved
just an inch or less from the front edge of the shelf? That's because
instead of having the books pushed back so their foredge is at the back
of the shelf, all the books are pulled to the front so the spines are
all equidistant from the front of the shelf. It looks nice and makes it
easier to read the spines. And seems like a much simpler way of dealing
with your problem.
Best wishes, Karen
