Query: Great information and very educational, but binding is lacking.

This book has been absolutely amazing and I've only utilized it for 4 weeks! It's easy to understand and has plenty of relevant examples to help the reader actually learn the commands and features of linux/unix. Although I love this book and will probably tape it together when it falls apart, it's biggest down fall is its binding; after 4 weeks it feels as if it may fall apart.
