OK, found the one I was thinking about as an extreme example. When I
was at The Black Hole before it closed, I grabbed a photocopy of the
Tektronix 4953/4954 Graphics Tablet Instruction Manual. Because it
was a photocopy they didn't have the large format originals for the
schematics in the back. Instead they had photocopied it piecemeal. I
scanned the photocopies and used Microsoft ICE to stitch together the
larger diagrams from the photocopies. When you look at the composite,
it's obvious they didn't have full coverage of the schematic, but
enough was there for MS ICE to get a reasonable approximation. I did
nothing but scan the photocopies and load them into MS ICE and it
stitched them together in a few seconds.
Look at the last two pages of this PDF:

If you get poor stitching and missing pieces,
then scan with more
overlap and use consistent exposure of the scans. If they vary
dramatically in brightness across pieces that need to stitch together,
it won't match them.
I don't have URLs handy, but I've used it a bunch of times for
contributions to bitsavers.
interesting! I'll adjust the process a little and give it another
try. thanks.
