CIPA is the law of the land, at least until a successful challenge is mounted. ALA is already setting up meetings with filtering companies to discuss the "library market". Don't forget, however, what Justice Breyer said in his concurring opinion "... the Act allows libraries to permit any adult patron access to an 'overblocked' Web site; the patron need only ask a librarian to unblock the specific Web site or, alternatively, ask the librarian, 'Please disable the entire filter.'"
Let's help our patrons [and librarians, and library directors, and board members] know their rights, shall we?
