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.

Is ready to hear that he is to have a visit from Willie Herschel. Regrets he cannot entertain friends as he used to. Has been laid up with ill-health. Would like information on how to prepare a chemical precipitate as that forming the sun's surface. Warren de La Rue has written to him.
A long letter dealing with the reports of various observers of James Nasmyth's 'Willow leaves' on the sun.
Is returning JH's paper on 'solar spots.' Comments on George Wilson of Glasgow and his suggestions on the use of telescopes. Encloses copy of a letter on the Moon's rotation. Was pleased to see JH's letter in the Times on the agreement between Scripture and Science.
