Design Pattern Repositories

When designing interactive experiences, there are lots of ways to innovate, but also situations where it doesn't make sense to reinvent the wheel.

Here is a list of libraries and resources culled from a LinkedIn group of user experience designers that I thought I'd compile for easier browsing:
