Deletion of Manuel Rosa

Comment: Please see  - the book fails all 5 criteria. As for your links, the first one is one of the authors' websites, so is useless in proving notability. The second is from another of the authors' websites, ditto. I have no idea why the 3rd link has been given as it doesn't mention the author, and is a personal website. The fourth does mention Roaa, but it is a self-published book (and as such is both useless in establishing notability and should not be used in the article). This actually confirms in my mind the lack of notability of both book and author
