A volume of a scope as wide as this is truly a joint collaboration that could not be completed without the help and support of various people and organizations. As often happens, this has been a longer road than what we anticipated at the beginning, but the process has been rewarding. We would like to thank all contributors for investing their time and effort into the project, and of course Brill for all the hard work and help in bringing the book to its final form. We are also grateful for Melanie Brunner, Lori Jones and Sara Elin Roberts for checking the grammar and to Ida Korppineva for her assistance in compiling the bibliography and the index. The volume has received financial support from the Centre of Excellence in the History of Experiences, Tampere University.
