Dunno really. When I scan a book I photograph the pages, usually at fairly low resolution for OCR. Any line art (or other) pictures I may photograph over again with more care and higher resolution. However, I don't know how relevant this is to your question. My books are generally either technical or of historical interest and I have not yet had occasion to prepare one on art as such. Accordingly I am more interested in producing a functional representation than an artistically adequate one. Cheers Jon

I see that the HTML versions of a number of PG works include images of art from the original books.

Are higher-resolution scans of those images available anywhere?

I'd like to experiment with automated vectorization of scans of line art, and providing SVG format vector files of the line art back to PG would make the effort doubly useful. (Encapsulated PS and PDF files also could be made available, if desired.)
