Leaves of Grass
First published AD 1855, written in English
Leaves of Grass is a poetry collection by American poet Walt Whitman. After self-publishing it in 1855, he spent most of his professional life writing, revising, and expanding the collection until his death in 1892. Either six or nine separate editions of the book were produced, depending on how one defines a new edition. The continual modifications to Leaves of Grass resulted in vastly different copies of it circulating in Whitman's lifetime. The first edition was a slim tract of twelve poems, and the last was a compilation of over 400 poems.
