Because I was advised to read this book and had good comments about it, I was really surprised to see even 1 single negative comment when starting my order process. I therefore started my reading with a sort of bitter feeling i was going to get either bored or over flooded with information.
Anyway, in the end I just want to point that yes it is a must read, but its writing could really be simplified. They also tend to repeat things alot, and suprisingly with the same words in a different order, which makes it very confusing, it's like finally understanding how something works and then looking at it in a mirror... I believe they wrote a very complex algorithm to write more pages ;)

If I could give it 6 stars...

For the last 5 years I have been writing C++ code, and discovering coding 'patterns' for myself. Each time, I thought that there must be a book out there which documents these 'patterns', and would save me months of work figuring them out for myself. This is that book, and it does not disappoint.
The 23 patterns are built on a set of core principles. I was aware of these principles before, but seeing their application in pattern after pattern has given me a much better and deeper understanding of how and why to apply these principles in my own code.
I would probably have used some of the patterns, some of the time. But after such a clear and deep explanation of each one, I now see opportunities to use the patterns frequently. And in each case, I realise why my code will be better with them than if I hadn't used them.
Reading this book immediately improved my coding skills by an order of magnitude.
This book belongs on the shelf of every C++ coder, alongside Meyers 'Effective C++' and Beck's 'Extreme Programming Explained'.

This is the one the others talk about

I read a couple of design patterns books before this one and quickly realised that I need to get this book as soon as possible. The others I've read all referenced it and as a design patterns catalog it presents patterns in the purest form. It is extremely easy to read in terms of clarity and layout and certainly in a format that will appeal to programmers. Although most examples are either in C++ or SmallTalk you should have no problem keeping up if you specialise in other languages including scripting languages like PHP5.

Not up-to-date but contains good guidelines

This book was recomended to me during my undergrad degree on computer science; is a milestone of OO Programming, is well written and only a basic skill of OO is needed to read this book.
Unfortunatelly the book doesn't cover modern topic as data persistence, but gives you an overview of the most used general purpose patterns.

must read

This is a good introduction to patterns and also covers some good implementation issues. It is an old book and the language samples show this - but patterns aren't language specific so this shouldn't be an issue if you focus on the concepts and problems the patterns overcome.
