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.

Proposes rules of procedure for use of secondary standards [see GA's 1853-2-7].
Thank you note upon receipt of the book of observations [see GA's 1853-2-1].
Question about whether the effect of Venus on the motion of the moon's node is measurable; this was brought on by reading J. H. Seyffert's writings.
Believes that the observations that concern JH [see JH's 1853-2-7] with respect to the moon's orbit do not argue for Venusian effects, but GA finds [G.] Seyffarth's writings disturbing, too.
Concerning GA's eclipse lecture and [G.] Seyffarth's claims regarding eclipse observations.
