Rankforest has collected nearly 2.3 million individual sales rank data points since the service began in 2005. If your book (or CD, DVD, etc) isn’t being tracked yet, add it using a free account.

Over the Thanksgiving holiday I updated some of the libraries and system dependencies that power Rankforest. The updates were primarily aimed at fixing security holes, but there might be a small boost in performance also. I hope everyone that could enjoyed some time off. More later!
