Here are the best short stories and novel extracts from the 2015 Pikihuia Awards for Maori writers as judged by Witi Ihimaera, Sir Wira Gardiner and Poia Rewi. The book contains the stories from the finalists for Best Short Story written in English, Best Short Story written in Maori and Best Novel Extract.
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.
This collection of stories was good. There were a few in Maori that I couldn't read, but the others were really emotive and descriptive. 8/10 I definitely recommend reading these stories. And I will be checking in on the previous collections, too.
