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.

Thanks for his letter, which had been forwarded to his old address. Is pleased he intends working on double stars, though 70 Ophiuchi may prove difficult. Will send some of his own readings for double stars. Like him, he is astonished at the acrimony of the attack on Thomas Young and the Nautical Almanac.
On behalf of [J. F.] Encke, asks that Greenwich observations be given to library of Berlin Observatory.
Is sorry to note the tone of CB's last letter concerning his projected biography of Dr. Thomas Young, but he means to carry out his project. Edward Sabine received £1000 from the Board of Longitude.
Does not wish to see HG's biography of Thomas Young until its publication. Anything JH submits must remain unaltered, with JH's name attached. Will not give reasons. Requests copy of Young's article 'Tides' in Encyclopaedia Britannica.
Has had a letter from Wilhelm Struve regarding the Standard. Could HK bring it to the notice of the R.S.L., and advise JH?
Writes to announce the birth of JH's and Margaret's first daughter, Caroline Emilia Mary.
Send Encyclopaedia Britannica volumes with Thomas Young's article on tides and T. R. Robinson's article on sound. When will HG's [biography of Young] be published?
Not interested in any contest of telescopes; will view objects desired by PB as they fit with JH's observational plans.
Misplaced papers are now found. HK must be 'first authority' on scale constructed for Wilhelm Struve. JH improved telescope by separating eyepiece lenses. JH's new baby girl.
Relieves ES's concern about the health of Margaret Brodie Herschel—all is well, and all around them are very helpful; wishes recovery for Margaret Herschel's sister Isabella.
Glad WS is coming to England but cautions that London empties in June. Congratulates WS on measurement of a 'great Northern arc.' Complains about the division of the Royal Society into 'parties'. Adds [James] South's results showing a sixth star, nearer than WS's fifth, in trapezium of Orion.
About the upcoming christening, the health of Margaret, and JH's concern about the tone of Charles Babbage's upcoming book.
About arrangements for the christening of daughter Caroline, and about the health of the family.

Sending a list of the stars to be observed to test the strength of his telescope.
