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.

Would like his opinion on a divided glass, double image micrometer before he submits it to an optician. George Dollond has lent him some divided glasses of long focus. Would like to borrow G. B. Amici's micrometer if JH could spare it.
Is much obliged for the loan of G. B. Amici's micrometer. Comments on some of his readings with it. Is sorry to hear of the ill-health of Lady Herschel.
Is grateful for the gift of the instrument and hopes to put it to good use. Will report on it when he has mastered its use. Hopes the country air is improving JH's health.
Results of observations using the G. B. Amici micrometer.
Is grateful for the copy of his Essays. Query about measuring the focal length of a double object glass. Gives results of his recent observations. Hopes accounts of JH's son are good.
Announcing the sudden death of his wife. The Taylors are with him.
Expressing condolence at loss of some member of JH's family [JH's daughter Margaret Louisa].
Sending a copy of a book he has found of great benefit. News of his household. Mrs. Gordon (JH's daughter Caroline) must have been shocked at the death of the Prince Consort.
Is grateful for the note and brochure. Is grieved to hear of the illness in his family. His own health is not good. Comments on the article on Telescopes by JH in the Encyclopaedia Britannica.
Pleased to hear that the memorial on behalf of Thomas Maclear has been successful. Comments on the mild weather. Hopes the health of his daughter is improving.
Thomas Cooke of York, a maker of object glasses, is about to visit Paris and would like an introduction from JH in order to visit the Paris Observatory. Hopes JH's son is back at Collingwood. Own health is poor, but is improving.
Thanks to JH's note Thomas Cooke was able to visit the Paris Observatory. His own health is slowly improving.
Regarding the spots on the sun known as James Nasmyth's 'Willow leaves.'
Is obliged for the perusal of Warren de La Rue's paper. Further comments on James Nasmyth's 'Willow leaves.'
Is sorry he has caused so much trouble with his 'Solar views.' Sends a recent paper he has written on the subject. Is appealing to James Nasmyth. Encloses sketch of an ear-shaped disc.
Would like account of the telescope of Warren de La Rue which JH has. E. J. Stone of the Royal Observatory has seen objects on the sun's surface like grains of rice.
Is ready to hear that he is to have a visit from Willie Herschel. Regrets he cannot entertain friends as he used to. Has been laid up with ill-health. Would like information on how to prepare a chemical precipitate as that forming the sun's surface. Warren de La Rue has written to him.
Was pleased to receive her note when Willie [William James Herschel] visited him. Hopes Willie will be happy in his married life. Was unable to accompany Willie to Aylesbury. Sorry to hear she has been unwell.
