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.

Asks GA for clarification of the value for the 'mean equatorial horizontal parallax' of the moon, since two different values are given by different authors.
Offers some thoughts on JH's problem [see JH's 1857-9-29], but needs additional time before commenting more fully.
Will send JS's treatise; wishes could offer something 'more intrinsically valuable' as token of gratitude for everything.
Is returning C. P. Smyth's paper ['Report on the Teneriffe Astronomical Experiment of 1856,' [R.S.P.T., 148, 165-], believing it now 'unobjectionable for publication.'
Thanks for photograph of the moon.
Has not been able to go to Kew Observatory yet. The photoheliograph has to await John Welsh's return from Scotland. A reflector with a diagonal mirror would be suitable for celestial objects. Has now removed to Cranford.
Thanks WW for letters. Has been visited by [ [J. B. L.] Foucault; impressed by Foucault's instruments. Notes large number of sunspots.
Is honored by his kind invitation to visit him, which he hopes to accept. Has great respect for JH's work.
