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.

Has been working on the rotation of colored discs. Would be pleased to show him some of the novel effects. Is surgeon to the local Grammar School.
Proposes to be at Collingwood on Tuesday next. Intends coming early so as to be able to carry out his experiments by daylight.
Hopes to be at Collingwood on Saturday at 2 o'clock.
Some years ago JH witnessed his experiments on the rotation of discs. Has written a paper on this subject and would be glad of his comments on whether he has chosen the right forms for the colors of the circle.
