That IS a big scam, mostly on the part of the publisher. I used to work in a college bookstore. We would get new editions in and figure out that the color of the pages was different, and that was the ONLY difference in the two books from one edition to the next. Sometimes they just fix all the typos. Sometimes they reword things or switch the chapters around, but if it's what the professor requests then that's what the bookstore buys.
Most of what I used to use in the field was based on previous troubleshooting experience. Many discrepancies were unique and took a little time to sort out. I carried a log book with me to record what worked and what didnt, over the years it helped me to diagnose problems faster and more accurately. The classroom never gave me this kind of real world experience. Now its people, machines are much easier to troubleshoot.
Darn right its a scam. There is no need to switch books this frequently to teach the same material. I can see switching them out every 3-4 years to keep the answers from being passed from class to class but as mentioned earlier math and english hasent changed in a long time. :notsure:
