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.

Sends thanks and very high praise for AH's first volume of Kosmos. Also comments on a number of other astronomical matters.
Discusses MS's light experiments. JH will present the results to Royal Society. Describes apparatus that may help her. Recently attended a meeting concerning continental magnetics and meteorology.
Hopes extracts from Mary Somerville's letters on her experiments with 'Coloration of Light,' specifically, 'action of rays on vegetable juices,' can be read to R.S.L.
Perhaps periodic surges in atmospheric waves noticed by WB will repeat. Speaks of 'new climate' for globe. Hopes WB can attend [B.A.A.S.] meeting at Southampton.
Is now finally empowered to order the telescope he inquired about [see JH's 1843-9-2].
Will give lecture on moon in which he will discuss its composition, the craters Kepler and Gassendi, plus generalities.
Has just seen mention of MF's latest experiments showing the connection of light and magnetism. Comments on these. Proves some of his own theories to be correct.
Asks WP to recall the particulars of an experimental session [see WP's 1823-3-11] where JH tried to demonstrate the polarization of light by an electrical current in a coil of wire.
On insurance tables for the benefit society; comments on AD's punning humor; JH has a chest cold.
Approves GM's price for making 6.5-inch telescope. Proceed with work, which must be completed in five or six months. JH must consult others before approving mounting and clockwork [see GM's 1845-11-18].
Details attempts to purchase Mme. Witte's lunar model for the 'Museum of Oconomic Geology.'
Cannot attend R.A.S. meeting to explain Mme. Witte's lunar model; will send notes of explanation. Busy with the publication of Cape Results. Will write paper on improved method of calculating double star orbits. Discusses relationships of periods of Saturnian satellites.
