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.

Hopes that letter from Mr. Langton does not mean more trouble. Flood has made 'Complete Prisoners' of residents at Slough. Glad that JH bought good horse. Advice on JH's laundry. Caroline Herschel's finances. Concern for Georg Griesbach's health. Regards from Susan White.
Has received parcel from N. M. Rothschild. Hopes money for the Robert Molyneux clock will soon arrive. Encloses some items for him in Thomas Catton's parcel. Please accept Analytical Geometry. Hopes JL's two volumes on astronomy will be translated into English, and encloses copy of additions.
If either of the designs please him, he will be pleased to advise; otherwise explain in detail what he requires.
Some comments on sun spots based on William Herschel's ideas; considering a collection of William Herschel's writings but publishers not interested.
Regarding errors and discrepancies in the tables of F. W. Bessel. Difficulty of dispatching books to foreign members.
Gratified that JH appreciates the astronomical legacy that she left at Slough. Explains that she returned to Hanover because she felt that 'it would be in vain to struggle any longer against age and infirmity.'
