"The report explores the various legal and policy mechanisms that are crucial for the free flow of information, providing guidance for policy-makers and other relevant users, for the creation of environments conducive to the freedom of expression. As this publication makes clear, freedom of expression is not just a by-product of technical change: it must be protected by legal and regulatory measures that balance a variety of potentially conflicting values and interests in a complex global ecology of choices. The impetus that this report provides for the prioritization of research in this field encourages further scrutiny of the multifaceted issues that govern the conditions for freedom of expression on the Internet. The findings of this research point to the need to better track a wider array of global legal and regulatory trends." (Preface)
