At first glance, the page looks almost exclusively about the anime, and searching for "novels" or "books" turns up Adaptation Deviation stuff. So to answer your question, it is in the proper namespace and should not need to be moved to Literature. Literature.Legend Of The Galactic Heroes can exist as a redirect to the anime page, or you can leave it be in case someone wants to make a page for the novels. Source works can share pages with their adaptations but they don't have to.
(Also, short-term projects is not the place for this sort of question.)

Sorry on the last part. I wasn't sure and I expected this to be short in terms of redirecting just in case... Or not.
Been looking at the Legend of Galactic Heroes page. I know that it started as a novel in 1982. So shouldn't it get a redirect to Literature?
