From J.D. Meier’s blog, the Patterns & Practices team have released a bunch of pocket guides – smaller and more focussed – based on the Application Architecture Guide 2.0

Here’s the initial list:

• Agile Architecture Method Pocket Guide
• Web Application Architecture Pocket Guide
• Mobile Application Architecture Pocket Guide
• RIA Architecture Pocket Guide
• Rich Client Application Architecture Pocket Guide
• Service Architecture Pocket Guide

You can browse them all here at CodePlex.
