A new law on child pornography will make it nearly impossible to distribute legitimate works of art, medical texts or television shows that contain sexual material, a coalition of publishers, librarians and editors says.

The law requires that anyone who produces material with images of sexual activity or "lascivious exhibition of the genitals" must keep rec-ords proving the models depicted are at least 18 years old.The group challenging the law said it would force librarians to remove from their shelves any medical, sex education and sociological texts showing full frontal nudity and stop magazines and TV shows from using adult sexual material that is protected by the First Amendment.
