A Book for the Masses
Overall, this is a great reference and beginner's guide to both system and network administration under Linux. The illustrated comparisons between NT/2000 and Linux simplify the process of porting a single machine or a network to Linux; clear language and general technical principles make the vast majority of the chapters indispensable to current Linux administrators and users.
If you are a librarian, don't waste time ordering and reordering. Don't worry about the books being swiped off the shelves--be prepared for it. This is the kind of book that opens up whole new worlds and "embiggens" the smallest technical minds. It's not perfect, but it's certainly comprehensive and comprehensible.
