For pages that you don’t need to use for a while, use the Archives option. Archiving a page will move it to a different screen, which helps keep your Page List more manageable.  You’ll only want to archive pages that you don’t need, since any archived page will not be visible on the website. Also, archiving a page will automatically make it unpublished and remove it from the search results.

To move a page to your archives, click the “Archive” link next to that page. You will be asked to confirm this action, and then the page will disappear from the Page List.

To restore an archived page, check the "show archived items" box at the top right of the Page List screen. You can then select the "Restore" link for any pages you would like to add back in.
