When you log in to AV4, you will directly access your library, where the digital books assigned to your account will be displayed. 

In the AV4 Offline application, to view and work with the books without an internet connection, you must download them. In the library, books that have not been downloaded appear inactive, with their cover in black and white. Once the download is complete, the book becomes active, and its cover is displayed in color. 

To download a book in AV4 Offline, you can do so through the “Download Options” icon located beneath the inactive book cover in your library. Several download types are available: 

• Download Light Version: This version allows you to view the book but does not include any associated resources or activities. It takes up less space on your device, and you can always download the resources later when needed. 
• Download Book with Resources: This is the full version of the book, including all resources and activities. 
• Resource Manager: You can download resources linked to specific units within the book content.
