I am not aware of the history of this cooperative venture, but I am somewhat disturbed by the fact that a group of people at Wikibooks are trying to have this feature removed without apparently letting anybody at Wikipedia know. ...
When I encounter a book at Wikibooks, such as http://en.wikibooks.org/wiki/Errata, I do not know if it is linked from Wikipedia. The Special:Whatlinkshere pages do not show links from other wikis. It is not easy to manually search Wikipedia, Wikisource, Wikiquote, Wiktionary, ... for links to particular books at Wikibooks, so I normally do not do this.
Further, most Wikibookians only put the deletion notice {{vfd}} on the front page of the book. Thus if Wikipedia links to a subpage of Errata, visitors can arrive at the subpage without knowing that we are considering whether to delete the page. I am not aware of any good way to fix this problem. -- [[Wikibooks:en:User:Kernigh]]
