their shelves. Testing books for lead would cost about $300 per book, according to a spokeswoman for the American Library Association, which has opposed the law. In 2011, President Obama signed HR 2715 into law, which exempted ordinary books from testing requirements. Coffee shops, second-hand goods stores, and others selling children's goods including books manufactured before 1985 may not sell children's goods that violate the lead standards. In order to assure themselves of the safety of those products, they may use a variety of means, the most reliable of which would be lead testing on the products. The CPSIA law had threatened sales of motorcycles and all-terrain vehicles built for children under 12, as internal parts of the bikes are built with alloys containing a small amount of lead. However, these too were also exempted under the 2011 amendment.
