James S. Heller, The Librarian's Copyright Companion (2012)
“ If one needest a password to access a digital work, thou shall not override password access; Thou shalt not avoid, bypass, remove, or deactivate a technological protective measure that limits access to a protected work without permission; Thou shalt not traffic in devices that have a primary purpose of circumvention; and Thou shalt not covet thy neighbor’s databases. Congress did toss a tiny bone to the library and educational communities. A non-profit library or educational institution may circumvent technologies that prevent access to a work in order to make a decision whether to acquire it. ”
