I am looking for this textbook for self-study:
https://www.pearson.com/us/higher-education/program/Franklin-Feedback-Control-of-Dynamic-Systems-8th-Edition/PGM1653583.html
ISBN: 9780134685717

I'm hoping the conglomeration here can help me track down a copy for less than $100 US. I would like a hardcopy of the US version. I've checked E-bay & Amazon The book is a pre-req for a course I hope to take in the Spring2021. I tried to take the course this spring, but it was a bit over my head. The prof let me borrow this book and it made sense, so I think it's the starting point for me. I would like the 8th edition because there's a small possibility that I take the course in the Fall2020 and this will be the required text. Any help is appreciated. #### MisterBill2 Joined Jan 23, 2018 7,013 College textbooks are always overpriced, and most of the theory about feedback control systems has not changed in 30 years. So in addition to the mandated text there are many that are just as good, and perhaps even better. #### SamR Joined Mar 19, 2019 2,576 In the interest of "Transparency", He did say that he wanted a Hardback copy. The International Edition is a full-sized and high-quality paperback. Textbook companies are a bit like drug manufacturers and have different prices for different countries. I don't even begin to understand the publishing business but I have bought used International editions and they are pretty much identical to the US edition except for the lack of hard cover material and resultant binding and much less expensive. They also sell it as an ebook at about the same price as the International edition. I will also note that there is very little difference from edition to edition and I believe publishers often issue new editions to cut down on their loss of revenue due to used book sales to students.

I don’t miss hauling around a bag of textbooks. I miss being about to quickly flip from one section to another. #### SamR Joined Mar 19, 2019 2,576 Me too... Much more difficult to find what I want by scrolling or searching vs. flipping pages. But I do like and use the PDFs. Not to mention that today's textbooks are HUGE! Also that by putting the PDF up on a large monitor makes it easier on my poor old eyes to see it.

It scanned over 1000 booksellers and found over 100 selling it.

I have also done well in college standing at the door of the last class that used the book I needed with a sign offering to buy the book. AND off-campus bookstores usually have better prices, especially for the used books..

Thanks everyone - I found a copy at my university library that I can use for a while (~1 month). I'll keep an eye out for a reasonably priced copy in the meantime.

Yep but that is the paperback International 8th Ed. and not the hardback US 8th Ed. he wants. Let me add that AbeBooks is probably the best used bookseller there is and my #1 goto.
