Several page types (or assets) can be borrowed into other locations. When you create a Borrowed asset type, the body of the original asset will display in that location. When the original page is updated, the borrowed version will update itself, and only requires publishing. Nice.
Borrowed Directory Page: Great for adding a faculty member to your directory who belongs to another dept.
Borrowed Feature: You have to have a Features listing folder to use this.
Borrowed (News) Story: Lets you put another department's story in your News section.
Borrowed (Content) Page: Use this to duplicate a content page in multiple places on your site.
