Help - Adding a Library
Adding a supported library is easy in the Library Extension. Follow the steps below to add your library.
Start by clicking on the icon of the stack of Library books in Chrome or Firefox. (Firefox on Android users should open the menu, and find the Library Extension entry at the bottom of the menu)
Pick your Country and State from the provided drop down boxes. Find the name of your library in the dropdown below the other two dropdowns.
Click on Add to add the library to the list of libraries in use at your library.
Choose the catalogs that you would like to see results displayed for.
You can repeat these steps to add any other libraries that you have access to and would like to see results for.
