Slight change made to biographical essay

I have altered the first sentence of Ed and Ken's biographical essay on Whitman by shortening the information on his birthplace to "in West Hills on Long Island." A user of the Archive from New York helpfully pointed out that the previous phrasing was incorrect, since West Hills is near Huntington, Long Island, rather than Hempstead.

Civil War correspondence added to the site

We have enhanced the site by publishing the Civil War correspondence of Whitman. Thanks go the NHPRC for supporting this work. In editing more than 600 letters, the Whitman Archive has created the first two-way correspondence treating these key years in Whitman's life. This contribution represents the combined effort of Whitman Archive staff at the Universities of Iowa, Virginia, and Nebraska-Lincoln.
