The Core Historical Literature of Agriculture (CHLA) site covers an enormous range of agricultural literature dating from the middle of the nineteenth century. The library suggests that the history of the United States can not be understood without attention to American rural and agricultural life. Thus the site acts as a virtual companion to a compilation of 4500 key documentary texts that have been identified and evaluated by a team of historians. The CHLA boasts over 1500 of these books and journals available online. Facsimiles of these works are provided in PDF format. The collection is searchable, or a researcher can browse the holdings by title or by author.
