Congratulations to Charles Severance, Clinical Assistant Professor at U-M’s School of Information, who recently announced the “second printing” of one of his books. High Performance Computing, published by O’Reilly–but out of print since 2003–has been republished on Connexions. Severance, with his editor Mike Loukides, worked with O’Reilly to release the book under a CC-BY license, then coordinated with the Connexions staff to republish it. The book is now freely available on the web and in PDF. Printed copies are available on-demand for the cost of printing and shipping. The CC-BY license also makes it possible for the entire contents of the book to be remixed and republished by anyone.
