Using previous edition books? (1 Viewer)

[Meeper]

Hey all,

I'll be studying sports science this year and I'm purchasing my books for a class. I have found previous editions and I've got my eyes set on two books. one of them has been published in 2009 and the other in 2010. However, my course requires the 2014 edition.

My question is, is it imperative to use the latest edition?

Cheers!

The older ones are likely to be identical, or close to it.
