Our textbook for this semester is Economics Principles & Tools, 6th edition by O'Sullivan, Sheffrin and Perez (ISBN-10: 0136076440 or ISBN-13: 9780136076445). You may use the reserve copy in the library on the main campus to stay current with reading assignments if you should experience a delay purchasing a copy.

Quite a few students have asked about using the previous edition of our textbook since they still have it from another economics course. I understand the need to do so given the co$t of this book. I have reviewed the current edition and do not see any major changes. I have not read every page, but the concepts, principles and theories are the same and consistent with how the tests and exams are constructed. You will probably be okay using the previous edition, BUT I cannot guarantee that there are not important differences between the two that I have yet to discover. There is a copy of the current edition on reserve in the library if you wish to make a close comparison between the two.

Some of the documents available within NS Online were created with Microsoft Word and Adobe.

You can download Adobe Reader from the Adobe Web site.
