John R Pierce also mentioned that it is hosted in Russia. I for one would definitely avoid this source. If I were to set myself a goal to get fundamental book I would wait a bit, as some clever people may recommend something else on this list, then choose what looks most fundamental to you. I would ask John Pierce and Jonathan Billings: what would you, gentlemen, recommend for the one who decided to become really very Unix (or Linux) person - understanding in-depth how the system works? Other experts (I know there are many on this list)? Thanks.
