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.

Francis Beaufort is on leave. Does JH know of Beaufort's intentions regarding instruments assigned to [William] Mann, who departs aboard Arab in two days?
R.S.L. policy for paying postage on scientific communication by members to and from foreign correspondents. Addresses of proposed recipients for Cape Results. ES's illness and problem with eyes.
Thought his letter had miscarried. Thanks for the gift of his recently published work [Cape Results]. Will be glad to supply any information from his own work on comets, which he hopes to send in the course of a few days. Is studying U. J. J. Leverrier's method of development by elimination.
Thanks for excellent Talbotypes. Notes how few photographs are 'perspective representations on a vertical plane' and suggests how to correct this.
WH notes that quaternions derive some interesting results in problems with three moving bodies.
Unable to explain how [Robert] Phelps received copy [of JH's Cape Results]. His name not on any list, and printer Peter Stewart did not send him one. Stewart requests copies be sent to John Ruskin and James Thomson. Will carry out JH's instructions for copy to Wilhelm Struve.
