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.

Regrets he was out when JH called. Thanks for the elegant verses. Will be moving shortly to a place nearer London, which promises much. Gives notes on some more sun spots, which he has recently observed.
Is grateful for his information. Believes he has found a way of overcoming the difficulties. Outlines his scheme for railway axles. Believes it will prove a great boon to the railways.
What does JH think of the idea of establishing a meteorological observatory on the Pic du Midi?
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.
Received JH's insertions. Will send proof on Friday.
Glad to have met JH's son [John]. Describes benefits of [R.S.L.] meetings for cultivation of science.
Asks JH to send an actinometer to Kew. It will be forwarded with other meteorological instruments to the Paris Exhibition.
Is grateful for his gift of Familiar Lectures and has read them with delight. Is pleased that J. M. Cameron's photographs have given pleasure.
Has been very busy. His poetry has inspired her to renewed efforts. Health not good.
Has only just received his letter. Feared for the safety of her parcel. Wishes he would write a poem on photography. John Taylor and the Camerons think that JH's poetry is beautiful. Writes in haste to catch the post.
Has heard a rumor that he is not well. One of his daughters has been recuperating at Hastings. Sends a paradox. Comments on the editing of Isaac Newton's book on Daniel by Benjamin Smith, his nephew. R.S.L. has produced Vol. 1 of the list of scientific papers. Blaise Pascal affair is in a lull.
Sends a theorem, which beats Blaise Pascal's by points.
Comments on AD's theorem [see AD's 1867-4-20].
Second National Portrait Exhibition will open to public on 3 May. Invites JH to private viewing on 2 May.
Thanks JH for his letter, and RW sends on additional writings in astronomy.
Had written previously to JH to obtain more information about JH's father, William. Is now asking JH for a response to the same requests.
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?
