The Chicago Manual of Style (CMS), now in its 16th edition, is the de facto a style guide for American writers. It deals with aspects of editorial practice, from grammar, usage, document preparation and much more.  The Chicago guide is one of many style guides for writers. 

The Microsoft Manual of Style, now just out in the 4th edition, attempts to do for the technical writing world what the CMS has done. 

Anyone who has read Microsoft documentation knows it has a consistent look and feel to it.  

The goal of the book is to help the reading create documents that are clear and concise. 

The book contains best practices for writing content for the web, optimizing for accessibility and communicating to a worldwide audience. 

This looks to be a really good title with a lot of fascinating information.
