Pity I didn't realise the second edition was out. Thanks amazon! There is an online version of the 2nd edition so I wasted 30 quid! In general it's a reasonable introduction to the most frequently used set of boost modules. It lacked the depth I needed for my project but the online boost documentation is excellent so I'd save your money and get online unless you are really new to boost.
This book is just the summary of all useful libraries in boost . It doesn't explain things in detail and let's u to search more in Internet . It could have more examples to explain api's . Still worth a buy for beginners.
