Eagle Library Question?

I would like to create my own library to make life easier when designing PCB’s in Eagle, is there a way to copy packages/symbols/devices from one library to another? Can’t seem to find the function within Eagle!

Thanks in advance

Regards

The easiest way that I know is to have your custom library open, then go to the main control panel window and find the part you want in the drop down libraries area. You can then right click on the part and ‘Copy to Library’ and it will pull the part into your open library.
