An interactive for last Friday's article about MIT's endowment incorrectly showed Stanford's 2012 endowment at $19.7 billion with a 19 percent increase in FY 2012. It is actually $17.0 billion, having increased by 3 percent.

The article associated with the interactive stated that "just over half" of MIT's 2012 operating revenues came from research grants. For clarification, MIT's operating revenues as listed in the Report of the Treasurer include revenues that support Lincoln Laboratory and the MIT-Singapore Alliance for Research and Technology.

Last Friday's review on Banksy: You Are an Acceptable Level of Threat incorrectly named Gingko Press as the publisher. The book is published Carpet Bombing Culture, and is distributed by Gingko Press.
