Updated catalog is available

Finally! The new PITCHf/x article archive, now powered by a back-end database thanks to Bryan Donovan, is available at the Hardball Times.

You can read all about it here.

 

Status of the catalog

Last year I diligently kept a catalog of articles written about topics related to PITCHf/x or using PITCHf/x data. Some of you have noticed that I have been negligent in updating that catalog this year. My last full update was January 15, and I did a partial update on March 1.

A new update is now in progress behind the scenes. Since the article list now exceeds six hundred articles, I’m working toward a database solution to better track them all. Hopefully, I’ll be able to unveil something within the next few weeks. In the mean time, Harry, if you would quit writing more than an article per day, that would help a lot. I should just rename my catalog the Cubs f/x Index.
