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.

JH cannot lay on too much of this kind of work, the closer in AR [Right Ascension] the better. Comments on the list of stars. The comet should be preceded by certain stars, some of which he cannot identify. If JH cannot see the comet for the trees come to the Observatory.
Captain [F. W.?] Grey has just been to the Observatory as he wished to ascertain the error of his chronometers. Outlines the signalling devices adopted. Fine definition last evening. Will call on Saturday if convenient.
Will retain JH's observations for a day to make a copy. Only knew of the arrival of the Governor [?] yesterday by the sound of the artillery. Intends to visit Cape Town, leave his card, and call back on JH. Expects new outburst of party spirit.
Understands from Francis Baily that JH has received the first 88 pages of the Parramatta Catalogue. The remainder has been sent and now encloses the final part.
Discusses readings made by his barometer and that sent from the Observatory by Charles Babbage. Sends publications concerning a new fossil and on geology.
