Texas Slavery Project

http://www.texasslaveryproject.org/   What is it?  Self-description:  "The Texas Slavery Project takes a deep look at the expansion of slavery in the borderlands between the United States and Mexico in the years between 1837 and 1845. Based at the Virginia Center for Digital History, the project offers a number of digital tools that allow users to explore the changing face of slavery in early Texas ...."   Need a some statistics, by area within early Texas, need direction to some primary sources (letters, laws, documents, etc.),  need some maps that show distribution of slaves and slave-holders across the years?  This is a notable place to come.   Torget's self-description: "Andrew J. Torget is the project's founder and director. Andrew is Assistant Professor of History at the University of North Texas, where he is completing a book titled Cotton Empire: Slavery, the Texas Borderlands, and the Origins of the Mexican-American War. Andrew received his Ph.D. from the University of Virginia while serving as the founding director of the Digital Scholarship Lab at the University of Richmond. He is also the co-editor of two books, Crucible of the Civil War: Virginia from Secession to Commemoration (University of Virginia Press, 2006) and Two Communities in the Civil War (W. W. Norton, 2007)."   An excellent website substantially derived from the work at the University of Virginia.   Does not address slavery among Native Texas tribes or the previous military system or peonage systems among the Spanish and Mexican elite, or the slavery in post-annexation Texas, or the prison labor system conducted by the state in subsequent years..
