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.

Skeptical over plan for galvanic illumination of wires. Has not yet seen J. B. Biot article; states he has always held Biot in high regard. Discusses naming of new planet.
Sends angular results from various astronomers using similar epoches.
Gratitude for [Cape Results]. Feels JH 'let off [James] Dunlop in a softer stile than he deserves.'
Thanks WS for copy of W. S. Jacob paper on American telescope. Hopes that Jacob will attempt Talbotypes of sun spots while at Aden.
Believes that Thomas Galloway's paper on solar motion deserves a medal.
Believes that if R.S.L. gives medals that year, J. R. Hind should receive one. John Lubbock is another possible candidate for his work on perturbation theory.
Suggests John Lubbock's improvements in calculating planetary perturbations be discussed at a R.A.S. meeting. Plans to bring subject before the Council.
Suggests WS take the chair at the next R.S.L. meeting. Discusses a project of John Lubbock's. Fears Caroline Herschel will not survive the year.
Sends paper by F. W. A. Argelander, which G. B. Airy wishes to have published. Revising chapter on perturbations in his Treatise Astr. Will include theory of motions of the apsides and the variations of the eccentricities.
Will miss R.A.S. meeting; asks WS to take chair. William Lassell announces discovery of Hyperion; believes he may have also observed an eighth satellite of Saturn.
Gives suggestions for Edinburgh Board of Visitors. Gives no specific names, but says it should include theoretical and practical astronomers, geographers, and meteorologists.
Compiles published work, unpublished work, and lectures; asks JH to proof the compilation. Discusses meetings of R.S.L. concerning charter by-laws.
Approves of James Nasmyth's application to join R.S.L. Describes good points of Nasmyth's telescope. Supposes that if he had drawing talent, he would sketch the members of the R.S.L.
Discusses the site of Cold Harbor. Visits the small personal observatory of J. G. Barclay, who WS thinks will produce good work.
Discusses Cold Harbor. Suggests the Duke of Bedford [F. C. H. Russell] could help secure a pension for Thomas Maclear.
