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.
Asked [William] Empson to write to JH about 'republication.' Thanks for [Cape Results]. Invites JH to visit. Glad that JH voted for [J. G. Shaw-]Lefevre [for M.P. from Cambridge].
Will send Edward Everett's copy [of JH's Cape Results] to Northumberland House. Everett was elected principal of Harvard College but resigned. Returns letter from Russian ambassador, F. I. Brunnov. Now that AP has sent copies to foreign sovereigns, JH will send to their ministers those copies destined for [observatories and institutions in] their nations.
