I'm not totally clear what you're saying. Namespaces give articles prefixes like "Category:", "File:", et cetera.

You can feel free to create an article with any prefix you want, like "Library:Example". But it will be ineffectual (it'll just be a normal article with a useless prefix) unless you contact Staff to have it created for you.
