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.

Thanks for letter. Will insert the information in a forthcoming issue of the Photographic News. Awaits with interest news of the new metals discovered by JH. Would like a small quantity of Junoniate of soda.
Letter and bottle of solution arrived safely. His latest photographic experiments. Is pleased to hear that JH approves of his efforts to chronicle photographic experiments.
Thanks for his interesting communication to the Photographic News and for the spectra. Gives details of his own photographic experiments with Iodide of silver.
His Daguerreotype arrived safely. Hopes to get some better photographs of the spectra before the end of the summer. Sees why their results differ.
Regrets that the article was received too late to appear in the current number. Will send a proof in a day or so. Would like to print some illustrations for JH's articles.
Invites remarks from JH. Except for W. H. F. Talbot's 'new discovery,' the subject of copying paintings draws the most attention from readers.
Comments on various specimen photographic papers JH is sending; JH believes he has isolated a metal he wants to call 'Junonium.'
Has just returned home and found the Photographic News and the queries regarding chemical experiments and photography. Gives details, but regrets he has not published much on it yet as he is still experimenting.
Sends spectra obtained by Ioduret of potassium. Gives details of his latest photographic experiments.
