You'll need to be working on the foreground of your publication when you add or delete pages. If you're not, remove the check mark next to Master Page (View menu) before using the following procedures.
Add a page
Any page that you add to a publication will contain that publication's layout guides and background objects.
Note If you're in Two-Page Spread view, it's best to add an even number of pages.
Delete a page
When you delete a page, only text and objects specific to that page are deleted along with the page. For example, if the page contains text from a chain of connected frames, the text will simply move to an adjacent page.
In your open publication, turn to the page you want to delete.
On the Edit menu, click Delete Page.
Note If you're in Two-Page Spread view, it's best to delete an even number of pages.
Delete the contents of
a page without deleting the page itself
Select either the objects or the text, or both, that you want to remove, and then press DELETE.
