With "P.G. Wodehouse: A Life in Letters" scheduled to be released this week, I was researching the book when I came across two additional books created by compiling the subjects' letters. I'm sure there are more, but today, I'll share these three, all published by The Random House Group publishing companies.
According the 
website, the Wodehouse book is "the definitive edition of P.G. Wodehouse's letters, edited with a commentary by Oxford academic Sophie Ratcliffe.  One
 of the funniest and most admired writers of the twentieth century, P. 
G. Wodehouse always shied away from the idea of a biography. A quiet, 
retiring man, he expressed himself  through the written word. His 
letters - collected and expertly edited here - provide an illuminating 
biographical accompaniment to legendary comic creations such as Jeeves, 
Bertie Wooster, Psmith and the Empress of Blandings."

"Orwell: A Life in Letters," published last year, features previously unpublished material, including letters which shed 
new light on a love that would haunt George Orwell for his whole life, as well as 
revealing the inspiration for some of his most famous characters. 
Presented for the first time in a dedicated volume, the selection of 
Orwell's letters is a companion to his diaries.
According to the publisher's notes, "Orwell's letters afford a unique and fascinating view of his thoughts on
 matters both personal, political and much in between, from 
poltergeists, to girls' school songs and the art of playing croquet. In a
 note home to his mother from school, he reports having 'aufel fun after
 tea'; much later he writes of choosing a pseudonym and smuggling a copy
 of 
Ulysses into the country."
 
Francisco Goya was an artist in the 1700s and 1800s. According to the publisher's information about the book, "Goya: A Life in Letters," from an early age Goya was anxious to preserve a record of his life, but
 few of his writings have survived and his most personal records appear 
in his letters.  He corresponded regularly with the aristocracy and the 
monarchy, as well as with friends.  Goya's surviving letters reveal a 
highly emotional man, prepared to state his feelings as passionately to 
the authorities of a Cathedral as to a close friend.  His letters make 
few concessions and are literary works in their own right.  Uniquely 
individual, they signal a new attitude on the part of a fine artist 
towards his profession, his social position and his sources of 
inspiration.
