Before striking out on his own to found and run the Digital Public Library of America, Dan Cohen was a history professor with degrees from Princeton (B.A.), Harvard (M.T.S.), and Yale (Ph.D.). His excellent blog reflects his academic research into the digital humanities, with musings on the past, present, and future of the book. Entries are written in an accessible and interesting prose. In addition, Cohen occasionally wades into library science, politics, religion, and other topics. Interested readers might like to start with the Best of the Blog, which features over two dozen articles neatly arranged into categories such as Digital Humanities: Theory & Practice, Scholarly Communication and Publishing, Mass Digitization, Google Books, Creating a Blog from Scratch, and others. The Podcast tab also links to over a hundred episodes of interviews, commentaries, and overviews of many higher education and digital humanities topics.
