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.

Forgot, in earlier note [see JH's 1862-4-2], to indicate agreement with GA's suggestions [see GA's 1862-3-31].

Reports the disappearance of a nebula seen by William Herschel in Coma Berenices, but which H. L. d'Arrest did not locate in 1850.
Thanks for HT's St. Clement's Eve. Has been reading it with much interest. Praises it.
Thanks for volume on physical geography and for encouragement at start of GS's career. Hopes JH will approve of GS's latest work.
Acknowledgment of receipt of more material from JH [see GA's 1862-4-3].
Was interested to receive the information regarding another missing nebula; would like to mention it at the R.A.S. The late George Bishop's observatory is now being rebuilt at Twickenham. Will return N. R. Pogson's table of Julian dates tomorrow. Has adopted the first of JH's suggestions.
Returns N. R. Pogson's tables. Has received a communication from [W.?] Lummis concerning a dark spot on the sun's disc. Has been unable to make any calculations yet.
Responds to WW's comments on JH's Iliad translation. Is preparing a 'General Index Catalogue of Nebulae,' with help from computists supplied by G. B. Airy. Asks WW to recommend JH's son Alexander for a professorship at the Andersonian University of Glasgow.
Informs JH of his grief over losing his son and his wife. His other son has left the military and now is helping AQ. Talks of Prince Albert's death. Asks JH not to forget AQ.
Needs to know, from JH, the date of the nebula observations [see GA's 1862-4-9].
Remarks on JT's papers on radiant heat and related role of moisture. Will send requested sample of rock salt. Explains difficulties using it and hopes JT will have better success, perhaps even repeating JH's experiments.
Responds carefully to the question of observational, and reduction, dates [see GA's 1862-4-12].
Finds JH's approval incredibly gratifying. Thanks for gift of rock salt. Is sending unscientific book; trusts JH's interests are broad enough to appreciate it.
Condolences on death of AQ's wife and son. Having lost a daughter, JH sympathizes. Discusses merits of Prince Albert. Lists Belgian Academy memoirs possessed to date. Mentions work on a general index catalogue of nebula. [J. R.] Hind's nebulae and others are disappearing.
Acknowledges receipt of more material from JH [see JH's 1862-4-13].
Has received notice from the Foreign Office that the Russian Government has sanctioned the establishment of a magnetic and meteorological observatory at Pekin.
Has now sent the last of the nebula observations to be reduced for printing [see GA's 1862-4-16].
