Normally, this database shouldn't ask for a login, unless you are trying to get to it from off-campus.  If that is the case, try it again, because we made a tweak on our end and now if you're off-campus you should get the login screen that asks for your Sewanee-related login:

username: your first and last name

password: your barcode number found by the barcode on your Sewanee ID (the number the library uses for you in our system)

If you are not off-campus and having this issue, will you let me know the path you are taking to get to Opposing Viewpoints
