The university's attorney can help to ensure consistency with existing policies, explain any vagaries in state law, and outline the university's rights which may transcend certain statutes. For example, the Oregon Supreme Court has ruled several obscenity statutes to be unconstitutional and has held that obscene communication is protected under the First Amendment. On the other hand, certain Oregon and federal statutes have been interpreted to give the university the right to infringe on the freedom of obscene speech if it is materially disruptive to the educational process. Universities also have the right to enforce reasonable regulations as to the time, place, and manner of speech and its dissemination. The attorney can provide valuable information on what is legal, prudent, and consistent with university principles.

The library may need to modify the statement to take special circumstances into consideration. If modification is necessary, the library's statement should follow the themes expressed elsewhere and avoid any deliberate or unintentional contradictions. As a rule, general statements are more effective than a long list of prohibitions. If the policy is too specific about what is not allowed, someone will think it is permissible to do whatever is not mentioned. A good policy will have a general statement about rights as well as responsibilities.
