The material contained in this publication is the outcome of the 8th International Conference on Human Rights "Right to Knowledge and Information in Heterogenic Society", organized by the Faculty of Law and Administration in the University of Warmia and Mazury in Olsztyn (Poland), in cooperation with the Faculty of Law in the University of Bari (Italy), which took place on 30-31 May 2008 in Olsztyn. The selection of issues in no respect can be called accidental. The summit of the European Council in Lisbon in March 2000 created foundations for creating society based on knowledge that is conscious in gaining information and equal access to knowledge. Individual actions of countries should aim at creating a human-friendly "information society" which allows creation of new working places and developing information and telecommunication technologies. This broad spectrum of problems which were the subject of the conference, interests not only Polish researchers but also scientists from countries like Italy, Spain, Ukraine, the United States of America, United Kingdom, and South Korea. They represent various cultures, which implies differences of opinion on many issues related to human rights. Publications included in this collective work are the reflection of freedom to express thoughts on difficult topics, which are important for all though.
