Three new initiatives to digitize information and put it online have been in the news lately.
1) The Boston Library Consortium, which includes most of the major New England colleges and universities (Brandeis, Brown, MIT, Tufts, and quite a few more) is working with the Open Content Alliance to digitize public domain materials in their libraries.
2) The papers of former Supreme Court Justice Harry Blackmun are being digitized and put online. (Hat tip: Volokh Conspiracy.)
3) Robert Heinlein's papers are being digitized and put online (although, unfortunately, you have to pay to get access to them). (Hat tip: Slashdot.)
