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.
Wilhelm Struve's observations support JH's findings concerning the rapid revolution of Eta Coronae. In acknowledgement of the discovery that double stars are a 'revolving binary system,' JH changed the inscription on William Herschel's monument.

Is trying to clean up JH's nebulae observations preparatory to leaving for the Cape; comments on communications from F. G. W. Struve about double stars.
Is grateful for GA's encouragement to prepare JH's nebulae observations for publication before leaving for the Cape; it now seems clear to JH that he cannot leave before 1833; JH has had further communications from F. G. W. Struve about double stars [see JH's 1832-5-4].
