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.

Requests another copy of WH's paper on light, recently read at Royal Irish Academy, having sent JH's own copy to Prague's [Karl] Kreil for description of [Humphrey] Lloyd's vertical magnetometer contained therein. Has WH yet found the three axes of the universe? Comments on WH's sister's 'charming' poetry.
In reply to WH's 1839-2-8 inquiry, JH believes that 'Skotodynamics' (the propagation of light waves) is a new line of research. Caroline Herschel is ecstatic about her Royal Irish Academy medal.
