The University of Michigan Digital Library eXtension Service (DLXS) provides the foundation and the framework for educational and non-profit institutions to fully develop their digital library collections. DLXS's impressive and comprehensive suite of tools -- including a powerful search engine and an array of class-based middleware -- has for years served as the cornerstone for digital library services and resources at the University of Michigan, including the Making of America collection, the Humanities Text Initiative, and the Library's Image Services program.
