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.

Answers to his queries regarding fees at Cambridge and amount of living allowance necessary.
Sending Part XI of his own Mécanique céleste. Comments on this work.
Has requested the government to forward payment for the clock. Regarding variations in the observations of F. W. Bessel, John Pond, etc. Has high opinion of Bessel's work. Has been sending books for Thomas Catton, but he never replies. How is Greenwich Observatory heated? Some observatories have troubles with dampness. Recommends book by K. W. Feuerbach.
Has received parcel from N. M. Rothschild. Hopes money for the Robert Molyneux clock will soon arrive. Encloses some items for him in Thomas Catton's parcel. Please accept Analytical Geometry. Hopes JL's two volumes on astronomy will be translated into English, and encloses copy of additions.
Thanks for books. Presumes Robert Molyneux has received payment for clock; this is a very good instrument, much better than [Thomas?] Young's. Encloses a work of his own, which he would like to see in the Transactions of the R.A.S. Sends propositions by a young Bavarian named K. W. Feuerbach.
Has doubtless received his Treatise on the Corrections of the Equatorials. Col. L. A. Fallon, head of the Austrian Survey, would like a Robert Molyneux clock. Can JH arrange to order one and send it via H. C. Schumacher. Encloses some notes on practical astronomy, which may be useful.
New Observatory is being planned on the lines of the new one being built at Obo in Finland. Would like an open letter from JH on the requirements for an observatory. Is there any news of the clock for [L. A.?] Fallon?
Had difficulty with actinometer observations on Etna, but obtained a few. Has just obtained a living in Somerset. Is working for the Encyclopaedia Metropolitana at the moment but hopes to make a set of actinometer observations soon.
JH's geological specimen is a piece of granular quartz, found in great quantities in Berks, Wilts, and Herts. JH promised to show him some of the garnets found by [J. S.?] Henslow in Anglesea.
Will send MS's communication about the theory of caloric to some scientific journals, rather than the Astronomical Society, where it would be inappropriate. Comments on caloric theory.
About matters relating to the building of the observatory.
Invites JH to London Institution to observe an experiment.
Is collecting and translating William Herschel's writings, projected for 4 volumes, the first one already being in press. Requests JH to provide additional biographical information about his father for one of the later volumes.
Letter of introduction for O. F. Mossotti.
Has no record of payee on draft from Caroline Lucretia Herschel's account sent to HG by JH.
Explains that because of illness, Mr. Schenk, a skilled instrument maker, will not be moving to London. [Much of letter is illegible, but it contains a draft reply from JH.]
Will follow JH's instructions. Expects to find inst[rument?] at home of Mr. Mowman or at Leicester Square.
SW's nephew Henry White is coming to Cambridge with message from [servant] Sally, who misses JH.
Hopes that letter from Mr. Langton does not mean more trouble. Flood has made 'Complete Prisoners' of residents at Slough. Glad that JH bought good horse. Advice on JH's laundry. Caroline Herschel's finances. Concern for Georg Griesbach's health. Regards from Susan White.
