The coolest aspect of the book is its tight integration with the associated website that has scads of observational data. Along with various software that lets you analyse the data for yourself. Any of you in research who've had to write software should appreciate the amount of effort that has gone into the coding of that software.
The book also provides you with a very recent (2004) assessment of the best current understanding of pulsars. With many references to the original research papers.
But the combination of text and website is a harbinger of future astronomy books, as volumes of data keep increasing. Traditional texts gave you no such access.
