The Humanities Text Initiative (HTI) has assembled an electronic archive of volumes of American poetry. Most of the archive is made up of 19th century poetry, although a few 18th century and early 20th century texts are included. The full text of each volume is converted into digital form and coded in Standard Generalized Mark-up Language (SGML) using the TEI Guidelines. The volumes already online, which include books of poetry by a number of African-American and women poets, represent a varied selection. In many cases, the texts selected are the only existing editions of the author's work.
