This will allow you to have sessions that don't time out quickly and to tag items.
First go to https://vufind.carli.illinois.edu/vf/Search/Advanced
Then, click on the link located on the toolbar--upper right corner of the page.
Then click on Create A New Account
Fill out the form
Now, when you log in, you can check this box and the time-out issue is meliorated--if not solved
The new interface also allows for tagging and "favorites." I haven't explored those functions yet.
