That's something that pisses me off. For the most part, it's un-needed changes in the texts that allow the book companies to do this.
Sure, some subjects have major changes as time goes on, but numbers don't change, so why do we need new math texts every year or 2? Same with MOST subjects...Things that are technological in nature are about the only areas that can justify new textbooks on a frequent basis as technology changes rather frequently nowadays.
History also changes of course...but USUALLY slowly enough that a new text every year isn't warranted.
But hey...remember, it's all about profit...and profit at any cost is good, right?
Yyyyyup. And it frustrates the professors too.
One of my professors mentioned it in class. One of our books went into the 10th edition, so the ones we had suddenly went way down in market value. He paged through and noted a few minor changes. His verdict: "Well that's a waste of money."
And professors who make up lots of their own lesson plans and examples, but reference the text frequently, rather than teaching straight from the text, have to go through everything and check stupid little shit like page and figure numbers. Notes for class, handouts, homework assignments - it all needs to get sifted through.
This particular 10th edition book was in the second edition in 1962. 9th was 2003. 10th was 2007.
Another one of my textbooks went 10 years between the 1st and 2nd editions.
The fun part: My professors say that engineering textbooks and handbooks from the
1940s are some of the best out there. New textbooks seem to get math majors in on some of the fun, and they start dealing with some ugly partial differential equations and such. I'm in the engineering technology program (B.S. degree in MET); we don't really do much with calculus, we use "canned" equations, without all the derivations. Nice algebra equations are a good thing, and a lot of the time, they're quite good enough to get the job done.
The good part: My now-outdated books will hopefully serve me well in the future. The information is still good; most of the changes are things like new homework problems, corrections to minutiae, and a little bit of new content that can be obtained elsewhere.
I've got a pretty good stack of textbooks now.
The bad part: No money from selling books back.
Well, almost. Books for gen-ed classes do get sold back.
The ugly part: Your face.
