We are grateful to all who have contributed to this Conference. Our special thanks go to the authors of papers and to the referees. The invited speakers give a particular flavour to the Conference. So do the moderators and the participants at the panel discussion. Sponsors and co-operating institutions gave us invaluable help, too. And last, but surely not the least, the strong international component, the enjoyable social events and a scenic environment have always helped to create a memorable atmosphere.

We are looking forward to seeing you at the 21st International Conference on "Information Technology Interfaces" ITI '99. We believe that ITI '99 will bring a growth in quality and abundance of the Conference activities and a further increase in the number of participants. We hope that you, the participants of ITI '98, will help us to achieve these objectives.
