Query: this is a copied book

This book is trash. This is just a printed version of textfiles.com that gives you all of the "lost" files for free. This is just a horrible book that takes advantage of people not using google first to find free information.I think this book is equivalent to somebody filling up a bottle with tap water and selling it for 20 dollars as pure water found in the most secret places.
