Notes
In citing correspondence from manuscript collections, give the full names of the writer and recipient, the date the letter was written, and the manuscript collection in which it may be found. The first time a collection is cited, its name should be given in full and its location should be indicated. Subsequent citations should abbreviate the name of the collection and omit location of the collection. For example:
