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 is busy correcting first proofs of pages on double stars. Thanks for binding JH's star [allineations?]. CP's suggestion [see CP's 1867-3-27] to JH's son Alexander, to collect and edit William Herschel's papers, entails too much work for one editor. JH dreads thought of such work. Doubts CP's claim that WH observed fixed star in Corona.
Comments on AD's theorem [see AD's 1867-4-20].
Thanks RW for sending RW's Mittheilungen and RW's Neue Untersuchungen. Replies to RW's queries about JH's ancestry and about the current state of JH's father's largest reflecting telescope.
About traveling to Halton; JH is finding working on his double star catalogue fairly severe drudgery.
Delighted to receive Memoir of Maria Edgeworth [ed. by F. A. Edgeworth, 1867]. Praises Edgeworth. Whom should JH thank for this gift?
Delighted to receive Memoir of Maria Edgeworth. Praises it and expresses thanks for it having been sent. Regards to Dr. Robinson.
