You can switch between different tabs on your Chromebook, so leave the Scavenger Hunt open in 1 tab, and open a new tab for the library website where you will find things you need to answer different questions (catalog, passwords).
If you accidentally close the scavenger hunt, you can just start it again. Note that the questions are in randomized order, so it may not look familiar when you open it a second time.
Be sure to read the hints before you ask for help!
Call #'s are on the bookshelves and on the spines of each book
