If an educator has created a content bundle for a special use case, like a virtual book bin or theme set, users can unlock access to these bundles in Sora. 

On the Explore tab, tap the plus sign at the top of the page. Then, enter the access code given by an educator or other school staff. You can type the numbers or copy and paste them. Then, click on Unlock Books. 

When you successfully unlock a bundle, you'll have the option to see titles or keep browsing on the Explore tab. If you enter an incorrect access code, Sora will notify you and give you a chance to try again. 

When you choose to see titles, you'll be able to browse and borrow digital titles from the bundle. You can return to your content bundles at any time on the Explore tab in Sora. You'll see the name and description at a glance, along with the expiration date. 

As a note, checkouts from bundles don't count towards user checkout limits, and titles can't be renewed or placed on hold.
