The new Knovel Digital Library interface requires an extra step for off-campus users. Please go to the Knovel registration page: http://app.knovel.com/web/register.html?orgregkey=c8f108bd-3389-4ba8-8fed-f23199287e61 to set up a personal username and password. Knovel will then recognize users from off-campus or off the network.
