The home page for System Center Configuration Manager on the main Microsoft website has general information about the product.  For technical information, start with the home page on TechNet which has links to resources to help you learn about the product.  See also the Documentation Library on TechNet for the online help (or the Technical Documentation Download page to download the documentation as a CHM, PDF or DOCX file).

The Information and Support for Configuration Manager page on TechNet has a set of links to further information about the product, including a useful query that you can customise to search the online documentation. Also on TechNet is the System Center 2012 Configuration Manager Survival Guide, a page with dozens of links to information about various aspects of the product.  TechNet’s FAQ is also useful.

Microsoft’s online Virtual Labs allow you to walk through labs for a number of Configuration Manager 2012 features by connecting to virtual machines hosted by Microsoft – full, downloadable instructions are provided.

The Configuration Manager 2012 forums can be helpful if you have a problem or are seeking more information about a topic within Configuration Manager.

Blogs

Microsoft’s two main blogs on the product are the System Center Configuration Manager Team Blog, and System Center Configuration Manager, which used to be known as the Configuration Manager Support Team blog.  They both have a range of articles about new fetaures, hotfixes, tips and tricks, etc and are well worth checking regularly.

Books

The most comprehensive book currently available is System Center 2012 Configuration Manager Unleashed by Kerrie Meyler, Byron Holt, Marcus Oh, Jason Sandys and Greg Ramsey (published by Sams, ISBN 978-0672334375). This book covers only the features in RTM, but a supplement covering the new features of SP1 and R2 is also available as a supplement.

Less detailed is Mastering System Center 2012 R2 Configuration Manager by Steve Rachui, Kent Agerlund, Santos Martinez and Peter Daalmans (published by John Wiley & Sons, ISBN 978-1118128985). It has been updated to cover the new features of R2.

System Center 2012 Configuration Manager: Mastering the Fundamentals, 3rd edition by Kent Agerlund (published by Deployment Artist AB, ISBN 978-9187445019) is also less detailed than the Unleashed book, and focuses on an implementation of Configuration Manager for a fictitious company.  The third edition includes R2 coverage.

Microsoft System Center 2012 Configuration Manager: Administration Cookbook by Brian Mason and Greg Ramsay (published by Pakt Publishing, ISBN 978-1849684941) contains straightforward instructions (‘recipes’) explaining how to carry out dozens of administrative tasks.  It’s very much a hands-on book, rather than explaining concepts in depth.

Exam Ref 70-696 Managing Enterprise Devices and Apps, by Brian Svidgerol, (published by Microsoft Press, ISBN 978-0735698093) is useful if you’re studying for this exam (which maps to course 20696).  It may also be useful for the 70-243 exam (which maps to courses 10747 and 10748), although it doesn’t cover all the subjects in that exam.  I’m not a fan of these books as they always seem a little brief compared to the exam.

All these books are available for the Kindle.

In addition, Microsoft have made available some useful FREE ebooks.  ‘Microsoft System Center: Configuration Manager Field Experience’, ‘Microsoft System Center: Software Update Management Field Experience’, ‘Microsoft System Center: Troubleshooting Configuration Manager’ are available from the Microsoft Virtual Academy website.  ‘Deploying Windows 10: Automating deployment by using System Center Configuration Manager’ is available from the Microsoft Press blog.
