Some research libraries in Stockholm (at archives and
museums) have put up book scanners that the public
can use. They have the same function as a public
copier, but you get your copies on a USB stick rather
than on paper.
This opens an interesting opportunity for Wikisource and
similar
Scan quality is excellent.
Yes, is a very promising way - my suggestion is, to get always scans in
TIFF (if possible; they are large but USB are large too ...), tro transform
them into an image-only pdf (which is the simpler tool to do this?) and to
load a copy into Internet Archive specifyng
