@Sarah_David0 When you click on "guidebook" you'll come to "your guidebooks." You'll see a gear icon in the upper left corner of any guidebook. Click on that. Then click "edit." You'll see "Add your recommendations," "Add a place," "Add a neighborhood," "Continue." Click "continue."
Then you'll see "Review your guidebook cover." Below that will be "Guidebook title" and "Cover photo." Leave them alone or change them, whatever you want to do.
Below THAT you'll see "Tell us where this guidebook should appear." And then, "Choose listings." Click on that, and then tick all the listings where you want it to appear.
