The Burrows-Wheeler Transform is one of the best lossless compression me- ods available. It is an intriguing - even puzzling - approach to squeezing redundancy out of data, it has an interesting history, and it has applications well beyond its original purpose as a compression method. It is a relatively late addition to the compression canon, and hence our motivation to write this book, looking at the method in detail, bringing together the threads that led to its discovery and development, and speculating on what future ideas might grow out of it. The book is aimed at a wide audience, ranging from those interested in learning a little more than the short descriptions of the BWT given in st- dard texts, through to those whose research is building on what we know about compression and pattern matching. The ?rst few chapters are a careful description suitable for readers with an elementary computer science ba- ground (and these chapters have been used in undergraduate courses), but later chapters collect a wide range of detailed developments, some of which are built on advanced concepts from a range of computer science topics (for example, some of the advanced material has been used in a graduate c- puter science course in string algorithms). Some of the later explanations require some mathematical sophistication, but most should be accessible to those with a broad background in computer science.

Saints, We Have a Problem Our world is in serious trouble Turn on the TV, log onto the internet, listen to the radio, read the newspaper, or just talk to the person next door, and you'll see what I'm saying is true. If it were just a problem for the world, that would be one thing. But, Christians today are finding themselves dealing with many of the same issues as the world, and we are not making the right choices when faced with these issues. We're choosing to follow the way of the world. What is going on? Unfortunately, the Church, the Body of Christ, has lost its feeling. What do I mean by "lost its feeling?" That's what this book will explore. Order your copy today and let our journey begin
