When you're using the EBSCO databases, you'll see an option to "sign in". You do not use your college login credentials for this; it is specific to EBSCO. Once you've created this account, you can save citations to online "folders." When you log in again, they will still be there. So if you are going to be using the EBSCO databases a lot, this is something you should consider.
By the way, using the "folder" feature without making a "My EBSCOhost" account is dangerous, because if you close your browser you'll have no way to get back to your folders.
