Libby is very easy to install and use, please see our Ebooks & More page if you haven't already installed Libby, and scroll down untill you see the app. When you have installed the app, you will use the set up menu (see the three lines in the center of the graphic on your Libby screen) to add a library (Thousand Oaks) and then to input your library card number and library PIN.
You can search for titles using the Q search link (looks like a magnifying glass or Q on the lower left of the Libby Screen) you can also browse by category.
