This is the third e-book in a five-volume electronic edition that includes the texts of every known letter written by Samuel L. Clemens (Mark Twain) from 1876 through 1880. The more than 700 letters published here have never before been gathered together and offered to the public in an easily accessible, organized fashion. Carefully transcribed and dated, they are presented here in a spare, unadorned manner, offering an unprecedented look at an important period in the life of this pre-eminent American author.
