While writing this preface, many of us are experiencing a horrible uncertainty concerning the fate of colleagues, friends, and members of their families. Globalization helped to develop social, cultural, economic and personal relationships. Therefore, not only the USA but also the entire world, which relies on democratic and human rights, has been hit and deeply hurt by the terrorists' acts of the 11th of September 2001. We are mourning with the victims and their relatives, and we are convinced that justice and freedom will prevail. The Program Committee and AACE believe that we need more global development and less isolation and marginalization. The WebNet conference as a global conference on the "networked world" can be one small contribution to a sustainable growth that decreases it is our pleasure to present to you the the so-called 'digital divide.' In this spirit, WebNet 2001. This conference addresses Proceedings of the Sixth WebNet Conference research, new developments, and experience related to the Internet, Intranets, and Extranets. The 452 contributions of WebNet 2001 presented in this volume were submitted from 51 countries. The volume consists of the Full and Short Papers accepted for presentation at the conference from a collection of 834. All submissions were carefully reviewed by at least three members of the Program Committee and their recommendations used for selection. Borderline cases were reviewed at a special Program Committee meeting where appropriate decisions were made based on re-reviews. Of the accepted contributions, five were considered outstanding based on the reviewer's scores and comments. The outstanding papers represent the top 1% of accepted papers. Authors of outstanding These papers are indicated in the conference Final Program. papers have been invited to submit extended versions of their papers to the WebNet Journal (www.aace.org/pubs/webne t). The coverage of the contributions is wide and gives the attendees of the conference the opportunity to learn more about innovative technological developments and practical experiences in many application areas. This is one of the features that distinguishes the WebNet series of conferences from others that focus on more specific areas. Our intention has been to provide a meeting place of developers, researchers, practitioners, and users as a forum wherein persons from disparate but related fields can fleet and learn about new developments that impact their professional lives. The major areas covered at the conference and presented in this volume include: Commercial, Business, Professional, and Community Applications E-Learning/Educational Applications Electronic Publishing and Digital Libraries Ergonomic, Interface, and Cognitive Issues General Web Tools and Facilities Personal Applications and Environments Societal Issues, including Legal, Standards, and International Issues Web Technical Facilities. These general areas have been divided into several more specialized topics. In addition to the papers included in this volume, participants at the Conference heard leading experts present Keynote and Invited talks; participated in tutorials, workshops, small -group discussions, and poster sessions; and had a chance to see demonstrations of various items of interest. The Conference was preceded by two days of tutorials and workshops, which conveyed the depth and breadth of the conference. Please plan to attend the next conference in Toronto, Canada, October 14-19. To be present and observe the WebNet series is one of the best ways to stay current with the rapid and intriguing developments of the Web. Periodically check the conference website at www.aace.org/conf for information Last but not least, we would like to thank all authors for submitting their work, and all members of the Program Committee, listed on the following page, for their cooperation and time spent reviewing submissions. Special appreciation is extended to Gary Marks (AACE), who is one of the main driving forces behind this volume as well as the WebNet series of conferences, and the AACE staff who contributed so much to the success of the conference.
