The East Texas Historical Association
You might consider membership in this regional organization, The East Texas Historical Association. They produce a very scholarly quarterly journal. The current issue includes, among many fascinating articles, a very good report on McKenzie College of Clarksville, which was organized during the time of the Republic of Texas and lasted through the Civil War.
Here is some information on the organization and how to join it, from their website:
Founded in 1962 on the campus of Stephen F. Austin State University in Nacogdoches, the East Texas Historical Association is committed to the preservation and enhancement of East Texas' great historical heritage and welcomes all who share our vision and interests.
Through our meetings, publications, and other efforts, the Association attempts to discover, collect, and preserve historical records, manuscripts, letters, journals, maps, pictures, and other materials related to East Texas history; to encourage the preservation of buildings of historical interest and architectural worth; and to publish and make known the rich history with which this part of Texas is endowed.
