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.

JH replies to RS's 1849-1-15.
Says he will guardedly write in his Outlines Astr. what he has to say about Neptune and the controversy surrounding its discovery. States that he eschews formulae.

A number of copies of the Cape Results were sent out, including one to Charles Ludwig Littrow [see GA's 1849-6-22]; JH will now try to trace the books whereabouts.

Asks GA if he knows of any rules or pitfalls in calculating time from earlier times [even B.C.] to the present.

Responds to GA's 1849-4-4, and sends the key.
Is making a case for JH's priority claims with regard to the means of determining double star orbits, in conflict with Yvon Villarceau.
