There are collections organized by composer for the American Songbook standards which feature the original "sheet music" (typically just a piano arrangement with lyrics, of the sort where either the composer or an arranger hired by the publisher knocks out "the" version to file copyright).
I don't have a link, but a number of jazz players have at least looked at these to get various added features not always found in the typical "Real Book"-type fakebooks: verses, the original "vanilla" chord changes, mostly, so as to get a clean look before deciding how to reharmonize the tunes, if desired.
You know, like
The Harold Arlen Songbook and those kinds of titles.
For jazz standards, I haven't seen anything more accurate and comprehensive than the Chuck Sher Real Books, which also include a number of regular standards, and even some more recent pop music. And, I think they preserve the Real Book tradition of including tunes from the album
Hotel Hello: what jam session doesn't feature those beloved classics!
(That's an old joke I heard somewhere if you sit in on a real book jam session: "How about a little "Hotel Hello?" It's actually a very good album, just not really mainstream in the way that the more usual jazz standards are.)
I don't know how these are distributed or sold online.
As for being forced to print instead of download, I haven't run across that, mainly because I already have all the Real Books and just use those in combination with transcribing the changes of recordings I like.
BUT, do they disable "printing to a file," for example, a PDF? I'd be a little ticked off at buying without that option.
