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.

Thanks for the interesting account of the star whose variability has now been established. Used the 3 1/2 foot last night and definition was good. Returns JH's letter to [James?] Dunlop and thinks there should be no offense taken. Opening for the Zenith is being enlarged. Measured JH's azimuth East and West yesterday.
Thanks for the perusal of Capt. J. A. Lloyd's papers. Comments on Lloyd's work at Mauritius. Does not think a mural circle necessary for the observatory at Mauritius. Regarding the Parade base line at the Cape. Not easy to put the guns into the ground.
Availed himself of the calm weather to finish the parade measurement. Gives an account of the work.
Talks about the very hot weather, and some matters of business that JH needs to work out with TM.
About the remarkably bright variable star, Eta Argus.
Some minor matters of astronomical business followed by an extended list of principles on which a constellation reform might be undertaken.
Gives latitude of 'this observatory' used in reduction of 'Comet stars.' Will accept systematic correction in all data to compensate for differences between TM's and Thomas Henderson's data. Instruments are erratic since telescope was moved. Using transit instrument only for sun, planets, and [reduction of Thomas] Brisbane's stars.
