Saddle up, kids, because it looks like Amazon's Kindle Library Lending service is inching its way toward launch. According to the Digital Reader, the retailer's OverDrive-powered feature has begun rolling out to two Seattle-area libraries, where some users have already succeeded in downloading e-books from their local repositories. Early testers are also reporting that they've been able to access a wide collection of digitized works using the beta service, with equipped libraries reportedly boasting "thousands" of e-books. Neither Amazon nor Overdrive have formally announced a rollout, but we'll let you know as soon as we hear more.
