MSDN Library is a library of official technical documentation content intended for developers developing for Microsoft Windows. MSDN stands for the Microsoft Developer Network. The MSDN Library documents the APIs that ship with Microsoft products and also includes sample code, technical articles, and other programming information. It is published and updated quarterly on CD or DVD. It is available for free on the web and on CDs and DVDs for paid MSDN subscribers. Initially, the disc version was only available as part of an MSDN subscription. However, after May 2006, Microsoft has started producing a community CD version of the MSDN Library freely available for download as ISO images on its Download Center which contains only updated content . The community distribution of the MSDN Library is aimed at developers in countries where broadband internet connections are not readily available. Also, the full MSDN Library images (not just updated content) for Visual Studio 2005 SP1 and Visual Studio 2008 are also freely available on the download center.
