It is our great pleasure to welcome you to the 21st ACM Conference on Hypertext and Hypermedia -- HYPERTEXT 2010. This year's conference continues the tradition of serving as the main venue for high quality, peer-reviewed, double-blind research on "linking" and interconnectivity, a tradition that now spans over two decades. The Web, the Semantic Web, Web 2.0 and Social Networks all demonstrate the value of the link concept. The conference continues to be an archival source for the latest work relating to hypertext, with a growing body of work that examines not only links between texts, documents, and media, but also between people.

The Hypertext 2010 call for papers attracted 90 submissions from around the world, of which 33 were accepted, included 18 long papers and 15 short papers. The program committee accepted papers on a wide variety of topics, ranging from literary hypertext and hypertext theory to social networking and adaptive hypermedia. The program includes the opening keynote speech by Professor Andrew Dillon, Dean of the University of Texas I-School, and the closing keynote by IBM Fellow Dr. Irene Greif. In addition, the conference features four workshops, two panels, 20 posters, and 3 demos. We expect that these proceedings will serve as a valuable reference for those interested in hypertext research.
