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.

Comments on GA's proposals about the storage of primary standards [see GA's 1853-2-7, i.e., RGO 6.341.30], and about secondary standards [see GA's 1853-2-7, i.e., RGO 6.341.31].
Talks about the means to introduce JH's radical reform ideas for coinage [see GA's 1853-2-12]; would like the Bank of England to go further in decimalizing weights of coins [see JH's 1853-2-11].
Responds about a meeting date [see GA's 1853-2-15]; further thoughts on the introduction of a new coinage system [see JH's 1853-2-14].
The meeting date is fine, but no hour or place has been specified [see JH's 1853-2-16].
Details of how coins are tested and stamped for weight. Procedures are not regulated, and variances are common. Encloses Mr. Miller's letter on decimal coinage. [JH annotation: 'Substance sent to Airy March 21 / 53 but altogether diff in form and wording.']
Responds with return of letter part and an invitation to the Royal Mint [see GA's 1853-3-21]; expands further on the coinage/weight problem.
Supports the report, but JH believes as an employee of the Treasury, he cannot sign the report on coinage to the Chancellor of the Exchequer; does not anticipate swift action on the report.
