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.

Comments on EH's 'Magic pictures', which JH said he produced and described in a paper twenty-six years earlier; JH is however unable to explain the process chemically.
Mostly about arranging a meeting with both JW and G. B. Airy at the Greenwich Visitation.
Writes a very kind letter, encouraging JS to remember the good days when JS and JH worked together in astronomy, and to forget less happy events. [This letter was enclosed in JH's 1865-5-31 to John F. South.]
As JH rarely comes to London. and is himself in poor health, it is unlikely that JH can visit James South. JH wants, however, also to wipe bitter recollections from his mind.
Comments on Charles Rümker's observations and agrees to a meeting [see John Wrottesley's 1866-5-12].
Responds to meeting arrangements [see GA's 1866-5-24].
Thanks JC for his papers on 'ice-cap and eccentricities [of planets].' Comments on the papers, noting the interactions between geology and astronomy.
Thanks for note [see JT's 1866-5-26] on improvement of the lecturing style of JH's son [Alexander]. JH's son has studied lecture's subject deeply and loves science; JH hopes will be physics professor at a 'considerable institution.'
Not well enough to attend Visitation Day at the Royal Observatory, but would be pleased if GA would invite JH's son John.
Reports JH's 1842 observation of a star near Epsilon Coronae, which may be tne new variable star [T Coronae].
Quotes from an 1840 publication by JH to show JH's priority over a recent request for a patent for 'Magic pictures.' Recounts some recent photographic experiments by JH on the action of light on platinum.
