It's a liability bonanza for any lawyers or groups that can win monetary awards against any offending institution if they can prove that children have been exposed to books printed before 1985.
I kid you not.
The American Library Association is taking this very seriously. According to their website:
(Books are to be held to the same testing standards as toys.)
"...the Association of American Publishers (AAP) have tested the components of books and found that the levels of lead in children’s books were far below the future legal requirements at the full implementation of the regulations three years from now. However, the advisory opinion from the CPSC says that not only must the testing be done by one of their certified labs but that this legislation also is retroactive, and every book must be tested. This situation will become even more complicated because the CPSC has not certified any labs to administer the lead testing."
The ALA is fighting this very hard; not to have books exempted from the "safety" prescriptions, but to have libraries exempted. (After all, very few children have been known to gnaw on old library books!)
