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.

Corrections on JH's manuscript on sunspots. Please keep alterations to minimum. Will send complimentary copies of Quarterly Journal of Science. Please write brief note on 'vaporous ring' and its bearing upon sunspots.
Photographic news. Has heard about the JHs.
Would like account of the telescope of Warren de La Rue which JH has. E. J. Stone of the Royal Observatory has seen objects on the sun's surface like grains of rice.
Thanks for his letter. Has no copy of JH's Cape Observations so cannot refer to them. Comments on articles on telescopes by JH; they do not lead him to adopt the arrangement he adverted to 10 years ago. Regarding priorities in discoveries.
Did not insinuate that RH plagiarized JH's idea of 'diagonal reflector,' but feels justified in defending JH's claim to being first to apply it.
Sends proofs and originals of plates [for JH's catalogue of nebulae], as directed by Mr. Churchill.
Cites quotation from Cape Results proving that JH invented the diagonal solar eyepiece. Discusses RH's claim. Note to JH accompanies this letter.
Doubts the claim that Auguste Comte has significantly influenced English scientists. Asks whether JH believes Comte has influenced JH or others. Asks whether it is more difficult to calculate the moon's motion or the motion of a projectile through a resisting medium.
As requested, sent six copies of Quarterly Journal of Science, No. II to JH and two to Russia and Switzerland. Publisher's policy prohibits sending reprints. Sends proof of JH's plate with suggested alterations to 'Willow leaves.'
Alterations to proofs of JH's plate [on sunspots].
Regarding a musical phenomenon pointed out to him by F. A. Gore-Ouseley.
Comments on observations of sun and sunspots, especially R. C. Carrington's book on the subject.
Just received photograph of JH, because Mrs. Gordon forgot to forward it. [E. R. W. Wyndham-Quin] Lord Dunraven is jealous and wants one too. Enjoyed visit of Mr. [Juetty?] and Mrs. Gordon.
Coincidences between observations of a meteor seen by EC and another account.
Demonstrates mathematically that sun's orbit cannot be elliptical.
Corrects error in sun's velocity that CR stated in earlier letter to JH today.
Meeting of the Standards Commission on 16 March.
In response to HS's query [1864-3-1] about the influence of Auguste Comte on English scientists, JH refers HS to JH's 1845 B.A.A.S. presidential address. States that calculating the motion of a projectile through a resisting medium is extremely difficult.
