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.
