The development and implementation of digital library systems have significantly improved processes for libraries as well as extended accessibility.


Researchers at the University of Michigan have developed tools, methodologies and training that can aid in the development of digital libraries, the DLXS suite of tools. XPAT, an essential component of the DLXS suite of tools, is a powerful, SGML-aware search engine, and an ultra-versatile tool for the development of digital libraries. XPAT provides excellent support for word and phrase searching, indexing of SGML elements and attributes, fast retrieval and open systems integration. DLXS also offers middleware (class-based tools to facilitate the delivery of digital library content to users) and training and support to assist clients in getting the most out of DLXS tools and methodologies. Please see for more information.
