Has anyone done this before?

The word library is often used for categorical collections. It could be a collection of refrence materials. Books or other forms of media like audio cd's, DVD's and magazines are forms of reference and entertainment. You could simply say you have a 'collection of hedgehogs' or use a thesaurus to find synonyms.
