Thanks Chris, Bernadette and Donna for your thoughtful answers. After considering your advice (and the resources you shared), I think it's worth a try. If nothing else, it will be a good experiment (and fairly low risk -- even though the pdf ranks #1, it's not a high-volume term). I think it will be important for the landing page to provide a really meaty, useful synopsis (as Chris suggested) that still offers some value on its own. Thanks again!
