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.

Regarding his projected supplement. Calculus of deviations. Naming of periodical functions. [John?] Spence's manuscript.
Hopes to visit him in a few days. Regarding the calculus of derivations. Periodic functions. Is taking up mineralogy.
Invites WW and [Thomas] Leybourn to join JH for dinner while Charles Babbage is visiting JH at Slough.
Accepts invitation to visit Slough and meet Charles Babbage. [Thomas] Leybourn may accompany WW. Seeking area of conic sections.
Discusses editorial actions taken by JH in editing mathematical manuscripts of William Spence, including materials recently sent to JH by JG.
Has sent JH's continuation of William Spence's 'Outlines' to press without any alteration. Gives the scheme adopted for the makeup of the volume. Hopes JH agrees; if not write at once as he is leaving London for some time.
Book will be arranged according to JH's wishes. Underwoods are to be the publishers. Is pleased JH has found signs of greatness in William Spence's works. Hopes JH will show this in his biographical introduction.
