Question: Examples of Challenges to Library Policies

Another paper (required management course- due in 3 weeks!!!)will focus on challenge policies themselves as guides to decision making.

I want an actual materials challenge case that confronted a library with an elaborate policy that dots every i, and to contrast that with a case where there was virtually no policy. Then I can posit the in-betwen one that lays out the essential bones and leaves implementation details to the people involved.
