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.

Has received a letter from U. J. J. Leverrier requesting a name for No. 59; sees difficulties; so would JH suggest a name. Has sent the Nautical Almanac supplement and a memoir by Yvon Villarceau to Smith, Elder and Co.
About WL's activity in setting up his observatory.
Sends series of solar heliographs. If further suggestions for improvement of these are noted, please send them. Is preparing to photograph Dec. 31 eclipse.
Gives account of observations on lunar radiation, including detailed description of experiments.
Clarifies that JT does not believe moon radiates cold itself, but effects are 'as if' it did. Relates this to atmosphere.
Thanks JH for compliments on his book [Theory of Equations]. Requests JH's signature for his application to the R.S.L.
Is sending him an engraving of his late father. Sees that JH has finished his work he told him about.
Asking JH to accept his book on the rock crystals.
Is pleased that JH likes his plates of Mars. Has a great collection of drawings of Mars but only a few of Venus. Hopes by the Spring to have the photoheliograph working. Has just completed his volume on the eclipse for 1860.
