A bill in Illinois would prevent publishers from charging libraries more than public for e-books and audiobooks. Unlike physical books, these books are temporarily licensed to libraries and can be costly to repurchase or lose access to them, a process that consumes taxpayer-funded library budgets. The bill, which passed the Illinois House without opposition, would prohibit publishers from offering electronic licensing agreements that restrict "customary" library functions. It would also prohibit publishers of restricting interlibrary loans or limiting the number of e-book or audiobook licenses a library could purchase. Author and publisher associations argue the bill puts the livelihood of those whose books fill library shelves at risk. The legislation mirrors legislation passed in Connecticut and is being considered by other states.
