Sometimes a topic comes at you from several different angles. Hopefully this allows one to see it in a broader fashion…
The college where I work just finished the first week of classes. Many students have incredible financial pressures when it comes to purchasing their required class texts ( see here, here, and here for three representative texts ). I am becoming more and more convinced that the current publishing structure for texts cannot survive. There will be a backlash, whether it be textbook rental systems at schools, or a new publishing mindset like the open text movement.
