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.

Comments on the possibility of employment in India for GA's son, Hubert.
Regarding employment for GA's son in the Educational Departments in India.
Thanks GA for receipt of some Royal Observatory publications; is still pushing the British metrical standard based on the length of the earth's polar axis [see JH's 1860-3-2].
JH wants to avoid using the meter in England; asks GA for the results of A. R. Clarke's calculations on the figure of the earth [see GA's 1863-10-7].
Is still not happy with the earth's axis as a source of standard length; sends JH the results of A. R. Clarke's calculations on the figure of the earth [see JH's 1863-10-8].
Is co-editor of a new quarterly scientific journal [Quarterly Journal of Science] and would be pleased to receive any contributions from JH, which would be liberally paid for.
Would JH's son [Alexander?] favor him with a resume of astronomical discovery for his new quarterly; if so, could he have his address?
Thanks for sending him his memoir on the Figure of the Earth. Comments on this. His son John would find a copy of this memoir of great assistance in his work in India; would he send him one.
Thanks for his comments on his memoir. Sends a few additions, which he will be submitting to the R.A.S. in due course. Will send a copy of the memoir to JH's son.
Thanks to JH's note Thomas Cooke was able to visit the Paris Observatory. His own health is slowly improving.
Comments on Greek fire lead JH into a variety of recollections.
