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.

Will be happy to abide by JH's judgement. Would like to know if the publication of the instructions in the manual would interfere with their separate publication. Will have to obtain financial assistance if his observations are to be continued.
As JH has accepted the superintendency of the Admiralty Manual he will try to undertake the geological part, but it will take time as he is busy on another project.
Has found that Orionus is a double star. Compares William Lassell's and Wilhelm Struve's observations of various stars.
Some additional details about JH's aunt Caroline [see JH's 1848-1-27].

Needs clarification about John Lubbock's planetary theory; thanks for G. B. Airy's lunar reductions.
Sends statement of JH's account [for publishing Cape Results]. Sales of book are less than anticipated but continually increasing.
Thanks JH for the gift of a copy of JH's Cape Results, and admires it greatly.
Gratitude for receipt of JH's Cape Results. Owning no instruments, EH appreciated JH's chapter on 'naked eye' astronomy. Notes and drawings of variable stars.
Informs JH that JH has been made an honorary member of the Physical and Natural History Society of Geneva; the Society thanks JH for a copy of his Cape Results. Comments on F. V. Mauvais's discovery of a comet and on the illness and death of Caroline Herschel. Will send comments on some of JH's astronomical work later.
Seriously ill. Will forward manuscripts to JH by next week.
Requested letters from [Hugh Percy] late Duke of Northumberland to JH offering to pay for publishing [Cape Results]. Hopes to include that debt in late Duke's estate, rather than as obligation upon [Algernon Percy] new Duke. Encloses receipt for £1,000. [JH note (20 Feb 1848): Sent receipt to TW. Expenses came within £50 of Duke's gift.]
Received drafts from WB and Charles Wheatstone for Admiralty Manual. JH must edit and connect them. Promises to preserve WB's intent and to give full credit.
