While we’ve always been very proud of the quality and quantity of the statistics offered here on FanGraphs, we have never had a proper place to explain exactly what they all are, what they mean, how they’re calculated, and how they are best used. That’s why we’re extremely excited to announce the newest section of FanGraphs – The FanGraphs Library.
Steve Slowinski, creator of the excellent SABR Library, has agreed to come on staff and maintain the Library here on the site going forward. He’s created an in-depth resource that will serve as a place for explanation and education on all of the metrics we have here on the site, as well as many of the principles that we often refer to. He’s added some extremely fun tools to the pages, including calculators which will let you reproduce the metrics on your own, charts that show not only league averages for each metric but also the spread of those metrics from best to worst, and links to various explanations of how these metrics were conceived.
It’s really a fantastic resource, and one we’re thrilled to have on the site. Steve will be blogging both over at the Library and here on FanGraphs, and we’ll continue to update the Library going forward. We hope you enjoy using this resource as much as we’ve enjoyed bringing it to the site.
