The Sir John Herschel Collection
The preparation of the print Calendar of the Correspondence of Sir John Herschel (Michael J. Crowe ed., David R. Dyck and James J. Kevin assoc. eds, Cambridge, England: Cambridge Univ. Press, 1998, viii + 828 pp) which was funded by the National Science Foundation, took ten years. It was accomplished by a team of seventeen professors, visiting scholars, graduate students, advanced undergraduates, and staff working at the University of Notre Dame.
The first online version of Calendar was created in 2009 by Dr Marvin Bolt and Steven Lucy, working at the Webster Institute of the Adler Planetarium, and it is that data that has now been reformatted for incorporation into Ɛpsilon.
Further information about Herschel, his correspondence, and the editorial method is available online here: http://historydb.adlerplanetarium.org/herschel/?p=intro
No texts of Herschel’s letters are currently available through Ɛpsilon.

In London to demonstrate gun cotton. Wants JH to mention his name to influential members of government. Promises JH will be surprised at its 'wonderful effects.'
Thanks JH for kind letter. Asks JH to write letters of introduction to various people. Thinks [Roderick] Murchison will give good advice.
Thanks JH for interest in his gun cotton. Will demonstrate its use next week. Includes list of items he will need to perform experiments.
