A "library folder" is a OneSearch folder/account (aka "My EBSCOhost" account). It is super helpful, easy to use, and easy to create.
If you are not already in OneSearch or one of the many other Ebsco databases like CINAHL, Business Source Complete, etc., go to the Library homepage and click the OneSearch button to access it.
In the database, you should find a "Sign In" link near the top right. Here's what it looks like in OneSearch.
Click "Sign In" and then click "Create a New Account." Set up your username and password. It is not tied to your UNF n#/password or email, so it can be whatever you want.
Now you are ready to use the Folder feature in OneSearch or any of the Ebsco databases. Just be sure to sign in before you start adding things to your folders.
