I don't know what precisely you wish to achieve.
But take a look at Doctorcomic's House Rules: Library from Peripheral Code #1 (see https://forum.atlas-games.com/t/peripheral-code-updated-issue-2-is-out/11082/1 ): it is made for ArM5, has Art and Ability scores for libraries, and lots of library Virtues, Flaws and examples.
Cheers
