The Open Knowledge Foundation created Open Shakespeare, an open license website with all of Shakespeare’s plays, introduced and annotated by volunteers. It also includes essays, words of the day, and the very useful ability to compare different Shakespeare editions in a side-by-side view.
While Open Milton sadly is still under construction, Open Correspondence is up and running. It has digitised correspondence of Charles Dickens arranged chronologically and by corespondent. In the long run, the project intends to upload the letters of Austen, Eliot, and Byron. We look forward to the Open Knowledge Foundation getting more Great Writers online and free to the public.
