What's a good starting book about software design patterns?

[Ronald]

I'm planning to buy a book and wondering which one would be a good start.

I got my eye on: Martin Fowler's Patterns of Enterprise Application Architecture

But I'm not sure if it's too deep into patterns already.

Have you checked Safari Books Online?

Check out Design Patterns in Ruby by Russ Olsen. Its an awesome book to start learning about design patterns without getting too bogged down in the theory.
Patterns of Enterprise Application Architecture is on my list to read too but I've heard really good things about it, so I'm sure it'd be a good choice as well.

It's on Safari for DL:

@Ron, do not buy the Fowler book yet. You will find it very hard to read if you are not into reading much. The Russ Olsen book is good.

I'm re-continuing to read Head First Design Patterns which I planned to read last holidays but didn't had the chance to actually read it.

Will checkout Design Patterns in Ruby.

Thanks!
