View Full Version : Book question...

Is it necessary to purchase the 9th edition? I can get the 8th edition locally, and am wondering if that is sufficient or if I need to order the 9th??

8th edition is sufficient, but there may be a few extra things in the 9th.

To my knowledge, the main difference between the 8th + 9th editions is that the 9th includes more discussion of digital techniques. But, as Mark said... the 8th should work fine for you.

Yeah, I used the 8th ed. as well. Just make sure you review the online 9th ed. study guide (I think Betsy has the link on her site?). The online guide was extremely helpful in test prep for me.

Yes, there's a link there, Steff.
