As the Campaign owner, when opening the Library when in a Campaign Lobby or Campaign Session you will be prompted to set a Game System (if you have not already) and to add books.
When you chose a game system, if any sources in the Library are core books, they are added to the Campaign Library automatically.
Books can be added by either:
clicking + Add books in the Library draw
by clicking the plus book icon in the top right. This will open a menu that shows you the list of books that you have access to.
when in a book in the Global Library use the "Add book to campaign" button located in the top right.
Additionally, you can purchase books by clicking Browse Marketplace in the Library Drawer to be taken to the Marketplace to find books to use.
When the GM configures the books in the library, two things are important to note:
Players can see the library, so they know what books are being used for this particular campaign. If they do not own a book, they will be prompted to go to the Marketplace and purchase the book.
The books in the library will add to the AI Assistant and AI Note's knowledge base, allowing for a customized and more accurate answers for Pro users.
The three dot menu for each book can be found by hovering over the book. A Campaign Owner can then hide books individually from the AI's knowledge base by choosing Hide from AI, remove books from the campaign by choosing Remove from Campaign, and Share Link to the campaign library.
