Using the library of an external swf

Hey everyone,
I’m looking to put all my resources for my project (a game) in external swfs, and so I was wondering how I could take objects out of the library of these external swfs, in AS 3.0.

Also, in terms of speed and security, is there any point in putting my images/animations in external swfs, compared to (for the images at least) loading them from a folder location?

Thanks,
