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 with great satisfaction on WD's observations, and their close agreement with JH's for many of the same double stars.
Comments on, and compares, WD's observations of several double stars with the observations of JH and other astronomers. In a postscript JH says 'The papers have told the truth for once—we sail sometime between Sept. and Dec.'
Sends some autographs requested by WD. Discusses observations of comets, especially Biela's, and of various stars, especially double stars.
