A proposal that would require school libraries to notify parents of every book their child checks out was advanced by Georgia senators Tuesday, while a proposal to subject school librarians to criminal charges for distributing material containing obscenity waits in the wings. The measures are part of a broad and continuing push by Republicans in many states to root out what they see as inappropriate material from schools and libraries, saying books and electronic materials are corrupting children. Opponents say it's a campaign of censorship meant to block children's freedom to learn, while scaring teachers and librarians into silence for fear of losing their jobs or worse.
