What is Accessibility of United States state law?

In the United States, some state governments and legal publishers claim copyright of public laws or certain publications of public laws. It has long been established that edicts of government are not to be subject to copyright protection in the U.S., but copyright protection for the selection and arrangement of published law may remain possible, at least in some jurisdictions. The primary incentive for state governments is the ability to charge for copies of the law or legal annotations. This is a list of the hindrances to accessibility, copyright or otherwise, on the legal codes of U.S. states.
