Connecticut became the latest state to introduce its own e-book bill, which would require book publishers who offer an e-book to consumers in Connecticut to also offer to license those same works to libraries on reasonable terms. Reasonable terms, according to the bill, means “to purchase or licensing specifications that consider publishers’ business models as well as libraries’ efficient use of funds in providing library services.”
Other states that have introduced e-book bills are Massachusetts, Rhode Island, Illinois, Tennessee, and Missouri. New York and Maryland's laws already passed. However, a few weeks ago the Association of American Publishers was able to obtain an injunction and stopped Maryland's law from going into effect, holding that the US Copyright Act preempted Maryland's law.
