Susan Haigh writes: “Whenever bestselling author Robin Cook releases a new medical thriller, the head of the public library in West Haven, Connecticut, knows demand for digital copies will be high. So will the price. Like many libraries, West Haven has been grappling with the soaring costs of e-books and audiobooks. Librarians in several states have been pushing for legislation to rein in the costs and restrictions on electronic material.

A bill was introduced in Virginia but was tabled in February.”
