Almost all library resources require you to login using the same username/password you use to access Blackboard or Lionmail. Your username is usually your first name, middle initial, and last name: johnedoe. Your password is unique to you.
Enjoy your resources!
That's it! You should now be able to utilize library resources. Some databases may require you to create a free account with them in order to download eBooks (like EBSCO). This is a separate account from your library account.
