However, public libraries are finding it a challenge trying to balance enforcing the new requirements and providing services to their guests. ‘Unfortunately, one of our managers’ cars was scratched with keys,’ said State Librarian Stacey Aldrich. Aldrich says since the vaccine and test mandate went into effect September 13, some people have been verbally abusive toward librarians who are trying to enforce the rule.”
