How do I add content to my site license?
If you have a multiple-user subscription to Stylebook Online, a site license administrator can add custom stylebook entries that are available to your users in searches and in the custom stylebook section of your subscription.
Your site license administrators can add notes to AP Stylebook material by going to the entry and clicking the "add a note or example" button below the AP Stylebook entry. They can also edit or modify an existing note.
