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.

Wishes all success to his proposed visit to Malta. Has been able to find the volumes of R.A.S.M.N. Comments on WL's system of levers for his telescope.
Is dismayed to find in the new edition of his own Outlines Astr. that he has attributed the discovery of Hyperion to W. R. Dawes without crediting WL; will have this corrected in a future edition.
Comments on WL's finding a sixth star in the trapezium of Orion [see WL's 1842-3-10]; lists other catalogues that identify that star.
Comments on WL's observation of the seventh satellite of Saturn as noted in WL's 1846-8-26.
Believes that the observations WL has made are quite sufficient to establish the existence of the seventh satellite of Saturn.
Announces, to WL, the discovery of a new planet beyond Uranus, gives co-ordinates, and urges WL to look for satellites 'with all possible expedition.'
Ask WL's permission to make reference to WL's sighting of the seventh satellite of Saturn in JH's observations of all the satellites of Saturn.
Urges WL to make public his observations of the seventh satellite of Saturn as Otto Struve is about to announce his observation of the same body.
Suggests names for the satellites of Uranus, in response to a request from WL [see WL's 1851-11-3].
Is pleased to hear of the discovery of further satellites of Neptune.
Some question of Harvard University observer having observed the satellite [see JH's 1848-9-22] one day before WL.
Congratulations to WL on his discovery [see WL's 1851-11-3]; naming should occur once the various satellites have been described and verified.
Is willing to assist in obtaining letters of introduction for WL's projected trip to Malta.
Is preparing a new edition of Outlines Astr., and would like to know from WL the status of each of the satellites of Uranus and Neptune.
Asks for details of WL's system of speculum polishing and telescope construction as JH is preparing an article on telescopes for the Encyclopaedia Britannica.
Comments on WL's information on telescope construction, and adds some of JH's own experience.
Comments on WL's 4-foot equatorial telescope of which WL sent JH a lithograph [see WL's 1860-2-8].
Comments on WL's nebulae diagrams and asks for more.
As JH is preparing a catalogue of all known nebulae, would WL please provide a complete listing of all he has seen.
