This is a 2-volume edition of Lucretius which will be coming up for auction at Sotheby's soon. Its estimated price is 8 000 -12 000 bucks (US). If we conservatively estimate that there are say, 500 pages between the two volumes, that works out to about 16 bucks a page if the book goes for the minimum. That's only about three dollars more per page than Ingenta is charging for reviews! Something is (hubristically) out of whack, no?
