Link/Append

Never mind. I solved the problem. Moderators, please delete!

Make sure you Append the data if you want to continue to edit it. That is the same as just loading it into the scene.It will be a copy of the original and any editing will not effect the original. Linking requires any editing to occur in the original blend file.

There is more to it but that is the basics.
