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.

About a variety of observations that JH has made.
Feeling very ill. Discusses adjustments to TM's transit instrument.
Asks TM whether he plans to work today.
Not surprised that the measuring rods broke; knew that they were top heavy. Discusses improvements. Very busy. A horse stepped on JH's foot, but no broken bones.
Weather was so unpromising that he sent off the men who were to repair the ravages to the base line levelings. Will JH therefore come on Wednesday instead of Monday provided the weather remains fine. Sorry he missed JH's request for barometric comparisons.
Had an unfortunate accident with the rods yesterday; one was smashed by the force of the wind. Intends to stake the whole line before the actual measurement takes place. Will calculate JH's Brisbane stars.
Sends the observations of the 21st copied by his daughter Mary. The leak in the center room has been repaired. Comments on JH's plan for measuring the base line. The Brisbane stars are nearly finished.
Weather is most provoking. Thinks it best to delay the action until Friday.
The flood has done much mischief to his baseline; there are still some holes to be filled in. Has written to Col. G. G. Lewis. Hopes to see JH at breakfast on Thursday.
