How do I correctly include copyright statements for included libraries?

Question

How do I correctly include copyright statements for included libraries?

I have a program that uses libraries which are licensed under the GPL and MIT (either jointly under both, just only MIT) licences.

How do I specify this at the top of a combined and minified file?

I have this currently:

My Program (GPL)
Copyright 2009-2013, Me

jQuery (GPL/MIT)
Copyright 2005, 2012 jQuery Foundation, Inc. and other contributors

Some other library (MIT)
Copyright 2013, Some other person

You mention all the copyright holders, that's all that's needed. The overall code must be under GPL, so you don't even need to mention that parts were originally under MIT; only files that are completely MIT-licensed should retain MIT license header.
