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.

Thanking him for his statement about solar motion.
Was surprised at the large vote in support of a parliamentary bill to abolish the British Standard of weights and measures; JH hopes bill will not pass.
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].
