This title features works by Pawel Althamer, Norbert Francis Attard, Nikos Charalambidis etc. This publication documents the programme Arrivals > Art from the New Europe, a series of 10 exhibitions being shown over two years at Modern Art Oxford and Turner Contemporary, Margate and introducing the work of artists from the expanded European Union. In addition, it invites specific questions around what does it mean, if anything, for artists, curators and cultural agents to be part of 'an expanded Europe'.
Various is the correct author for any book with multiple unknown authors, and is acceptable for books with multiple known authors, especially if not all are known or the list is very long (over 50).
If an editor is known, however, Various is not necessary. List the name of the editor as the primary author (with role "editor"). Contributing authors' names follow it.
Note: WorldCat is an excellent resource for finding author information and contents of anthologies.
