Abstract: The Portal to Texas History serves as a gateway to Texas history materials. The Portal consists of collections hosted by the University of North Texas (UNT) Libraries in partnership and collaboration with over 280 Texas libraries, museums, archives, historical societies, genealogical societies, state agencies, corporations, and private family collections. With a continuously growing collection of over half a million digital resources, The Portal to Texas History stands as an example of a highly successful collaborative digital library which relies heavily on partnerships in order to function at the high level. The proposed book chapter will describe all aspects of establishing the collaborations to create the Portal including the background of the project, marketing the initiative to potential partners, partnership roles and agreements, preservation of all digital master files, technical infrastructure to support partnership models, promoting standards and good practice, funding issues and development, research studies to understand partner benefits and user groups, sustainability issues, and future research directions.
