I read lots of criticism of textbooks, but I find little I think imagines the future of the textbook aside from replacing it with some as yet to be determined alternative. I want a clearer vision.
I have turned to those who offer perspectives on the future of other media. One of the best books on this topic I have read recently is Geeks Bearing Gifts by Jeff Jarvis. Jarvis is a CUNY journalism prof who writes about new media and changes to journalism.
