I revamped the blogroll and broke them out into separate subjects. I now have links under professional organizations, people (research or practitioners), publications (from scholarly journals to books), research groups, and software. Now that I think of it, I should have another category for databases that will keep soccermetricians from having to reinvent the wheel.
So if you have something that falls under one of these six categories, please send it to me and I'll place it on the right column of the blog. Thanks again for visiting!
