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.

Returns the papers of John Forbes (on mathematical subject) and comments on them. Suggests what the R.S.L. should do in such cases.
Arrangements for meeting with AD.
About a number of new associate members of the R.A.S.
The tract JH means is by L. A. Sédillot on the history of astronomy of the Arabs. Comments on this. Possesses it but it is bound in with a lot of other papers so is too heavy to send. Would he give John Williams permission to open letters addressed to the President of the R.A.S.
Asks for reference to date of discovery of the moon's variation by Aboul Wefa.
Arrangements about meetings and signing of the R.A.S. testimonials.
Has been hunting JH's proposition through the books and finds that it has dropped out of use, though the older geometrical books include it.
Arrangements about how the R.A.S. meeting will proceed.
Would he trouble himself about the address only; all the rest will be arranged for him.
Returns H. P. Brougham's (Baron Brougham and Vaux) paper. Does not recall any similar theories, but does not think his own theories are shaken by those of Brougham. Finds that AD has already done extensive work on the calendar.
Finds that some of the pages from the paper JH recently sent him are missing. Please send if he still has them. H. P. Brougham (Baron Brougham and Vaux) does not mean to attack the undulating theory. Regarding solar spots and the surface of the moon.
On return of a paper, and approval of AD's method of resolving fractions.
Regarding the early history of the calendar. Comments on the various versions.
Sends AD part of JH's paper on double stars; concerned about AD's dating it on arrival.
Another part of JH's double star paper; question of priority between JH and Yvon Villarceau.

Correction to paper on double stars following up JH's 1849-3-26; a terrible pun sent on by JH's wife, Margaret.
Needs to revise Outlines Astr., and will include Ernesto Capocchi's announcement of the discovery of another planet; some further corrections of JH's double star paper.
