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.

A note of instructions about paying for the Cape telescope [see GA's 1845-12-20].
Regarding the condition for determining the best possible orbit for a double star.
Did not realize that JH would leave town so quickly. Cast a 10" speculum successfully after William Parsons' (3rd Earl of Rosse) plan. Is having difficulty with his grinding and polishing and would welcome JH's advice.
Is grateful for JH's letter. Has already had criticisms of the chapter, which JH mentions. Will reconsider it.
Has just been showing Michael Faraday some of his experiments on the influence of magnetism of bodies slowly precipitating; comments on this and will be pleased to carry out any experiments for JH.
Returns to JH, and comments on, the distribution lists [for the B.A.A.S. star catalogue].
Please notify ES of date for the council [of B. A. A. S?] to meet. Oxford is most eligible of Southampton invitations. Sir Robert [Inglis] is best candidate for president.
Writes in thanks for JH's kind words on several occasions about FB's ideas on psychology.
Sending him the elements of the new planet Astrea. Orbit is based on the Berlin observations. Differs from those given by J. F. Encke.
