I took a look at what our practice has been regarding labeling of wikibooks. I found all sorts of things. We've been adding a lot of authornames, especially when the title is generic and the author name helps to distinguish one book from another, and using "Wikibooks" as the "author" of these books feels appropriate. I will be adding a PR to make this a uniform practice.
