-MG author Mike Jung explains what diversity means to him and why it’s important.

-An example of how authors are being hurt by the Amazon-B&N war.

-YA author Matt De La Pena talks about his visit to a high school in Arizona, where one of his novels has been banned from the curriculum for — essentially — having a Mexican-American protagonist. Also see the New York Times article on the visit and the issue of Mexican-American studies being made illegal in Arizona.
