Google have launched an interesting new resource - an online quarterly book called Think Quarterly. In normal parlance you'd probably consider it on an online magazine or periodical but, semantics aside, the first issue is an excellent looking collection of articles themed around data.

Google describe the purpose of Think Quarterly as offering some necessary breathing space from the busy world we live  in:
At Google, we often think that speed is the forgotten 'killer application' – the ingredient that can differentiate winners from the rest. We know that the faster we deliver results, the more useful people find our service. But in a world of accelerating change, we all need time to reflect. Think Quarterly is a breathing space in a busy world. It's a place to take time out and consider what's happening and why it matters. Our first issue is dedicated to Data – amongst a morass of information, how can you find the magic metrics that will help transform your business? We hope that you find inspiration, insights, and more, in Think Quarterly.

The list of contributors and articles in this issue is great, including the likes of Hans Rosling, the Guardian's Simon Rogers, Google's Chief Economist Hal Varian and Guy Laurence, CEO of Vodafone UK. I'd urge you all to take a look.
