To ensure adults' access to constitutionally-protected speech, while at the same time protecting minors from "harmful" materials on the Internet, public libraries could take a three-pronged approach that would pass constitutional muster and leave the role of child rearing to the family:

1. Public libraries could install privacy screens so that information accessed by patrons on the computer would not inadvertently offend other patrons or librarians.
2. Public libraries could provide both filtered and unfiltered Internet access, either through separate computers or filtering software that could be turned on and off.
3. Library cards could contain a "yes" or "no" bar code that would tell librarians that parents either have approved their child's use of unfiltered computers or that they have not.
