Here, you will see featured resources at the top of the page, which displays the four most viewed/downloaded resources. The area below is where all of the library resources are located. On the left-hand side is the Folder Pane that displays folders/subfolders. You can browse through the folder pane by expanding/collapsing folders by clicking the (+) and (-) icons to the left of a folder. Click a folder to view only its resources on the right.
The Resource Library is expanding all the time, so check back often!
