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.

Rejoices that RH is studying orbit of Mu2 Bootis. Suggests way to simplify calculations. Compares orbits for Gamma Virginis calculated by various observers. Notice of systematic errors.
Sends a copy of an ephemeris of Biela's comet for November and December.
Has just completed the orbit for the binary star Mu2 Bootis. Sends details. Could not send his notice of Biela's comet to W. R. Dawes as he did not know his address.
Is grateful for details of his method of calculating the orbits of double stars. Comments on some of his observations.
Will apply JH's principle at the first opportunity. Has made some successful observations of the star Epsilon Arietes. Intends observing Castor on every fine evening.
Communicating the elements of Castor and Corona by JH's method. Comments on these readings.
Sending him the elements of the new planet Astrea. Orbit is based on the Berlin observations. Differs from those given by J. F. Encke.
