Open Source Enterprise Publications - Existing

Obviously I wasn't the first to think of how open source operating systems can present value in an enterprise environment. From what I can tell most of the dated literature focuses on open source application development in contrast to open source operating systems in a business environment. I did some queries to see what's already out there and available for free or via the library. I think I might have found some valuable sources. I am going to take a look at these and see what kind of approach these source reflect in terms of effectively using and deploying open source in a business environment. Let me know if you know of any other publications about this topic. The sources below aren't in any particular order:
