As the author of the book a "Sara Oldfield" is shown. This is wrong, the book was edited by Dirk Kaesler and has a lot of different authors for the different chapters. Please see here http://www.amazon.de/Aktuelle-Theorie... and please fix this.
We can't use information from Amazon for anything in this database. I was able to find the book on WorldCat and updated what information I could (including the Editor).
Thanks a lot in advance!
