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.

When his packet is ready for the Cape, forward it to him at the Admiralty and he will arrange for it to be sent. Congratulations on the new addition to the family. When next in town perhaps he would be interested in seeing the new object glass for the Cape, which William Simms is preparing.

Has traced the comet notified in J. F. Encke's circular. Gives his readings for its position. Has compared the stars near it. Hopes JH's family are all well.
Now a long time since she has written but she has happy memories of their last meeting. Is anxious about the posthumous fame of her son. Would be pleased to hear news of the family.
