The volume has 25 chapters organized into four sections: the global challenge, meeting the global challenge, new research methods, and delivering better care in the community. The authors are the leaders of mental health services research and practice throughout Europe, with a smattering of contributors from South America, Asia, and Australia. Almost entirely absent, however, are authors from North America. Some of these international authors have written in our services research journals in the United States; we have been encouraging it here, in Psychiatric Services. Some of the authors of our papers in the United States have published papers in journals elsewhere, but for the most part, our worlds have been too separated. This edited volume is an important bridge between these worlds.
