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.
Astronomische Nachrichten 1392 compares positions of forty nebulae by G. F. J. A. von Auwers, H. L. d'Arrest, and P. E. Laugier. Calculations for JH's [Catalogue of] Nebulae are complete and ready for inspection.
Not surprised that actual costs [of publishing JH's catalogue of nebulae] departed from estimates. Reports vote by [R.S.L.] committee. Does not believe publication will be expensive.
Returned JH's 'original sheets of nebulae.' Kept sheets of calculations. Will write about money accounts later. Lord Palmerston's communication about Thomas Maclear's pension.
Received £10 for cost of reducing JH's 'Catalogue of Nebulae.' Send description of catalogue.
Accounts for money spent in reducing JH's catalogue of nebulae. Encloses sample page from catalogue and Astronomische Nachrichten No. 1392 [see JH's 1862-11-18].
More corrections of errors [in reduction of JH's catalogue of nebulae].
