Uno straordinario progetto internazionale che vede coinvolti 4 fra i maggiori editori d’Europa: altraverse (Germania), Kana (Francia e Belgio), Planeta Cómic (Spagna) e Star Comics (Italia).
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.
There is not a single story I liked in this volume. Very disappointing since I loved the first 3 and enjoyed the initiative, but it looks like perhaps they stopped believing in it themself? Even the voting system is stuck to vote the volume 3 in November, when we are almost in February and volume 5 will be released soon. I guess no voting for this volume 4?
Let's just say that it looks like they invited talents and then they ran out of options and accepted random people with stories that are boring, mostly with bad drawings and not able to properly write a dialogue?
Again very sad, because I enjoyed almost all the stories of previous volumes and I loved different of them.
