The list of chemistry titles at eg http://www.ebooks.com/subjects/88.smm is looking impressive (although at first glance, so are the prices). Has anyone bitten the bullet and recommended etexts for student courses etc (or actually know anyone who has purchased such?) Mind you, when one looks at the formats available for ebooks (http://www.ebooks.com/help/tools/readers.smm) you have to wonder whether it represents a real advance from print. -- Henry Rzepa.
