One of the first things we're trying to solve with the library is its isolation from the rest of the great content on MSDN and TechNet. For example, when I'm reading product documentation on Windows Server, how easy is it today to jump over to the KB articles or downloads related to Windows Server? Not very. We want to bring together all of the content related to Windows Server (for example) into a "Center", which exists today, but is a somewhat fragmented experience that shoots you off to different sites for downloads or for library content.
We have some prototypes up now of a new kind of TechNet and MSDN that shows how we'd integrate the "library" experience into the "center" experience. We'd love your feedback on these prototypes.
