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.

Sending the Eloge on G. C. L. D. Cuvier. Plans to write a biographical memoir of Cuvier herself.
Is grateful for his letter and offer to show her any G. C. L. D. Cuvier letters. Was pleased to see his letter as she heard he was at the Cape in pursuit of constellations. What shall she do with the forthcoming copies of her book on fishes he ordered?
Introducing A. T. D'Abbadie, one of his scientific friends.
Must see him on an important matter.

Passing on E. J. Cooper's information that he has found a new star. Congratulations on another addition to the family.
