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.

RC's book [Observations of the Spots on the Sun] is done. First copy, exhibited at R.A.S. last week, was well reported in R.A.S.M.N. Will send copy to JH.
Formulas for determining rotation rates of sunspots relative to latitude on solar surface. Believes equatorial parts of photosphere are dragged faster than others. Speculates on rotation rate of solid body below (if such exists).
Copy of RC's book will be sent to JH from R.S.L. Thanks JH's son for letter.
