Tracking one author across multiple publications. Possible?

Let us say I like an author. Ed Glaeser, an economics professor at Harvard. He contributes regularly to Economix (economix.blogs.nytimes.com), but he also writes for other publications. E.g., an article in TNR ( http://www.tnr.com/article/books-and-arts/what-city-needs?page=0,1 )

Unless Glaeser maintains a Twitter feed or a blog and updates it when he's written something new, there's no comprehensive way to track his mainstream publications. (He has neither.)

Has someone developed a method of aggregating content like this and consolidating it in the form of an RSS feed or tweet stream?
