There should be, like, a Federal subsidy program to pay publishers to make digital editions of old books.
(I don't mean scanning them in and OCRing them. The Internet Archive does that already, the effectiveness of OCR is limited, and they're constantly constrained by copyright.)
There's a ton of knowledge in books older than, say, 2010 that ought to be more available, but may not be judged profitable to republish in digital formats by the publisher that owns the copyright.
