Insurance

The board of trustees of a public school district library owns the library building. A private club occupies the entire second floor.

Is it required or advised that the Friends group (ours is a separate non-profit) have their own insurance?

We are a small, rural, association library that serves a population of under 4,500.

Is there professional insurance for librarians? Given the book-banning lawsuits, do librarians and library workers need additional insurance to cover possible lawsuits?
