Hi, here's a pointer to follow up on the earlier discussion on how to integrate Google books viewability API into closed legacy systems that allow only limited control regarding what is being output, such as III's Millennium system. Compared to other solutions, no JavaScript programming is required, and the integration into the vendor-provided templates (such as briefcit.html etc.) is reasonably clean, provides targeted placement, and allows for multiple uses per page.
