The first thing you will want to do is visit the Gabriele Library page on Immaculata's website.
From there, you can access the databases from the top bar of content:
On that page, you will see databases listed both alphabetically and by subject matter. I do not recommend searching using alphabetical order unless you already know what database you need. You can go to the subject list and click the most relevant for your class. If you have no idea where to start, go to the General Use Databases which directs you to databases that hold a large variety of content. 
When accessing a database, you may be directed to the screen below to log in to your Immaculata account. After this page you will be redirected back to the database.
On the main library page you will see the WorldCat Discovery Search. This search bar works similarly to Google searching, and will allow you to put in your search term and search across the catalogue of physical materials available at Gabriele Library, as well as Open Access materials and materials throughout our available databases.
