I'm taking a course with this book right now... and yes, I stole it at the authors' recommendation. Textbooks are too expensive and I don't want to carry it around anyway.

I think that it's legal to copy a book it if the author says it's ok to copy it... but don't quote me on that.

Only if the authors are also the copyright holders, ironically that is rarely the case.
