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.

Giving his views on the desirability of establishing a Midland Observatory.
JH is now very supportive of EL's intention of establishing a Midland Observatory following EL's 1849-11-12.
Recommends Edward Sabine's work on terrestrial magnetism for Royal Physical Medal, and joint award of Copley Medal to WP and William Lassell for improvements in reflecting telescopes.
Supports proposal made by C. M. Elliot to execute 'running survey' of India with instruments from observatories.
Reply to RD's 1849-11-8.
[Responding to JF's 1849-11-23], JH cautiously discusses various considerations bearing on the idea of sending an astronomer and a large reflecting telescope to the Cape.
Agrees that it would be desirable to make further observations at the Cape, but foresees difficulties, especially liaison with the Astronomer Royal at the Cape.
