TitleZ is a new site that is free while in beta. Using TitleZ you can compare current and historical Amazon sales rankings on literally thousands of books.
The tool is predominantly for authors, publishers and book marketers, but it has value to really anyone interested in tracking consumer trends. For example, if you're a consumer PR pro or marketer, you can use the site to track a bunch of books across a particular category. For example, by tracking books, oh say, about iPods you might be able to get some insight into whether see if the meme is still heading skyward.
Thanks to Mindy Roberts for emailing this over.
