Abraham Lincoln Letters Online at U. of Rochester

The Lincoln and His Circle web project "seeks to digitize
and make available the letters to, from, and about Abraham
Lincoln that are held in the collections of the Department of
Rare Books and Special Collections at the University of
Rochester...[t]hese materials are found, for the most part,
in the papers of William Henry Seward; the Seward Papers
were donated to the University by William Henry Seward III
(1945-1951) and Lincoln materials were the gift of the Fred L.
Emerson Foundation of Auburn, NY (1987)."

You may browse the collection or search by keyword, writer,
recipient and date range. Letters are digital images of the
original documents.
