Share the entire Content Library of one notebook to another. For example: It’s the beginning of the quarter, and you want to populate your new Algebra 1 notebook with the same material from last quarter’s class. Or, you can keep a master Class Notebook and distribute its Content Library each time you're preparing to teach the same course again.
Open OneNote desktop, then select the Class Notebook tab.
Select the Content Library you’d like to distribute.
Select Distribute Content Library. (For Mac: Copy to Content Library.) Use the checkboxes to select the sections of your Content Library you’d like to distribute.
Select the notebook(s) you are sharing to, then select Copy. It may take a moment for distribution to finish.
