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.

Having been provided with answers by JD to some questions by JH about color-blindness, JH now comments on them and offers some theoretical considerations.
Today's newspapers confirm shocking report heard last night. Imagines loss and ruin to members. Confident that exalted character of PS's uncle will result in uncle being found blameless. Certain that James [C. Stewart], as new partner, could not bear any shame for magnitude of this long-standing problem. Hopes PS's mother will bear up well. Offers to assist Mrs. Stewart financially. Grateful that James had not yet left for Munich before this happened. Margaret is in shock.
Offers JF advice about the telescope mirror [?] and looks forward to seeing JF on his way to France.
About observing binary stars. JH has decided not to accept the offer of passage on a war ship to the Cape of Good Hope, as he wishes to be beholden to no one for the results of the expedition.
It appears that Peter Stewart, MH's brother, is fighting some kind of battle, the outcome of which will affect the whole family. JH wants to help and offers £5000 through MH to Peter. JH has just completed writing his Treatise Astr.
JH is 'immersed in my nebulae . . .working day and night for dear life'; also found another double star. Urges MH to come to Slough with her mother and brothers.
Will check to see whether JH has a spare telescopic mirror JH can give TH. Comments on observing Gamma Virginis and other double stars.
