Using old AP prep books: Good idea or not?

Is it a good idea to use Barrons AP Micro/Macroeconomics 3rd edition (2009) for the 2016 exams and Barrons AP Chemistry 7th edition (2014) for the 2017 exams?

I don’t know whether the Micro/Macroeconomics courses have been changed since 2009 and whether the 2014 Chemistry edition covers the changes in the AP Chemistry syllabus. I think it has, but I want to be sure.

What are some other prep books for other courses that are old but perfectly usable for current AP tests?

Thanks!
