What often happens is they get donated to book bank-type programs which give away the books for free. I've been volunteering at one for a few years, and we get a lot of free books from publishers like that.

He can't challenge the validity in court unless he is harmed by the law - he has to have standing to sue. If he gets sued now, he can bring up the issues.

This test is still in use today.

IANAL, but this does have a legal history in the US and is much better than it used to be. All these doom-and-gloom "what happened to the US" posts ignore that obscenity law used to be much, much stricter.

Watergate? If the offense is particularly egregious, getting it out in the open is usually enough to force change.
