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.
After collecting and reducing all nebula observations by JH and William Herschel, JH objects to GA's suggestion that JH should pay for calculations needed to prepare catalogue of nebulae. Hesitates to request additional funds from R.S.L.

Concerned about 'Commercial weight' of new standard of weights and measures.
Sends GA's correspondence on the subject of the Admiralty grant, with further explanatory comments [see JH's 1848-10-28].
A note to accompany further copies of correspondence to the Admiralty [see GA's 1848-10-30].
Reliability of measuring instruments used in scientific and public surveys. Approves George Peacock's suggestion to revise survey tables for use by non-scientist surveyors. Schools should teach only legalized systems of weights, measures, and money.
JH responds with an assessment of the Indian observatories [see GA's 1866-9-24].

Asks JH's opinion about GA's plan not to print a separate volume of magnetic and meteorological observations for 1848.
