Some librarians already sued for harrassmnet. The library settled for a large sum, likely to avoid setting a precedent. Say, why don't you write up your experiences and I'll post them on my group's web site??
Sure. I could tell you stuff about porn and the public terminals. For example, the Dean of library established a policy that prohibited us from "hassling" anyone viewing "adult material" regardless of age. I am not kidding. Eventually, the policy changed to allow us to kick minors off terminals if they were viewing porn.
