Photoshop and Illustrator are great for creating and editing original content but not for compiling your content for publication. InDesign is good for original content creation as well, but its primary role is PUBLISHING.

Here you can layout books, business cards, and brochures. It works for hard-copy printing as well as e-documents. You can even create Apps! If you need to share your info with the world this is a great tool to bring it all together.
