Lately, i have been doing more and more style guides to guide my clients in their online presence.
Last week, an excellent article “Getting Started With Pattern Libraries”  by Anna Debenham was published on A List Apart explaining the steps to take for coding and maintaining a pattern library. Anna explains how she did the ALA style guide, for web designers to use as guidance. She also wrote a book about this Front-end Style Guides, published by Five Simple Steps.

I collected valuable pattern libraries and style guides for over a year, i publish them here for reference and guidance and also because i made a few little style guides for recent client projects myself.

I'm sure other pattern libraries will be published soon and that's a good thing, it helps us - web designers - a lot. In case you want to add other style guides or pattern libraries, please suggest one.
