Can these papers be downloaded? The greatest concern with any web-based solution is reliability. A PDF might not be as easy to grasp as a web-based solution with live examples and graphs that make the content more approachable but it is still worth gold since I can back it up and have it available whenever I need it. Web-resources on the other hand can become unavailable at a moment's notice.
