On the Open Library System, I note that high resolution gray-scale scans (at least for the one project I checked) are not archived, though the black and white scans are
it's my understanding that d.p. has kept all scans, but it's reasonable they wouldn't mount the high-res ones; no sense letting the general public burn your bandwidth. this, of course, is the problem with high-res files in general. they're nice to have, for purposes of "preservation", but you can't really make them "accessible" in a practical way until computer resources become free across-the-board, so -- in a practical sense -- they don't really do any good. it's not just bandwidth, either. storage problems quickly ensue when each page of a book eats multiple megabytes. and computers need lotsa power to crunch through them. and sure, we can all see the day coming when all of these resources _will_ be available to us. but how soon is that? are you willing to bet on it? and don't forget that you are a lucky first-worlder. how soon until _everyone_ on the whole planet has unlimited computing resources? really? are you willing to bet on it? and if the third-worlders can't have what you lucky people have, how long do you think they will sit on the sidelines without a full-out revolution? we need to think in real-world terms, and be _practical_...
I also note that there is no 'bulk' download function to get a zip of all the files associated with a text.
yeah, that would be nice. will d.p. offer that? who knows? in the meantime, you can learn the address of an image by right-clicking it and choosing the appropriate menu-item. for instance, here's the u.r.l. i recovered for one page:
http://pgdp01.us.archive.org/1/pgdp02-archive/texts/documents/43e52c83dd501/... subsequent scans have the same u.r.l., except "002.png", "003.png", etc., so it's very easy to scrape them en masse. (if anyone needs a scraper-program, just backchannel me.) -bowerbird
