Simerjit and I co-authored this book, so firstly, thanks everyone for the positive sentiment. A LOT of hours went into this so I really do hope people benefit from it.
Justin, which library was this by chance? I hadn't heard that libraries would be holding the book so this is great news. I plan to donate copies to my local libraries also.
The books is available everywhere online both in physical and kindle editions, you can also find it on the O'Reilly online training subscription service.
