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.

Regarding the deeds for CB's brother-in-law. Is sorry that CB could not see the blasting of the cliffs at Dover.
Thanks for his paper on the Earth. Wishes his own Cape work was finished and of the same standard as FB's work. Regarding support for Dr. W. B. O'Shaughnessy when his election to the R.S.L. is being considered.
Will start work on the Southern Constellations without delay. Thanks for his remarks on W. B. O'Shaughnessy.
Agrees to provide Josiah Quincy with extracts from letters by James Grahame. Highlights of Grahame's life.
Thanks for the 'exquisite specimen of Daguerreotype.' Speculates on the possibility of making Daguerreotype portraits small enough to be set in rings or in shirt pins.
