Hanover Historical Texts Project
"The Project's principal aim is to make primary texts readily available to students and faculty for use in history and humanities courses. The texts scanned for the project are all in public domain. The electronic forms of the texts created by the HHTP are under copyright. Permission to copy and use the texts is granted for educational purposes. We ask that you acknowledge the Hanover Historical Texts Project. Permission is not granted for commercial uses." The texts are presented by areas of the world and then by time period.
