Mark G. Sobell's freshly revised reference work on Ubuntu Linux may be the most impressive computer book I've seen in the last 10 years. If you are currently stranded with a pile of abandoned computers on a desert isle, I'm telling you, this is the book.
When my review copy arrived, I met the postman at the door, and immediately wondered who might have sent me a box full of lead fishing weights. Or perhaps it was shotgun shells, I guessed, hefting the package. Opening it, I found instead 1,200+ large-format pages, on high-quality paper, all obsessively cross-referenced and indexed to a "T".
This is not a book you can sprawl out on the couch with, and enjoy casually paging through. I tried it at first, since that is my usual reading attitude. But it will crush you. Your cushions will flatten permanently under the weight. Eventually, your fingers will fall asleep, you'll drop it, and your cat will find you hours later, semi-conscious, babbling something about the bash shell.
No, this is a book that you must clear a wide berth for on the table that holds your monitor and keyboard (You may need to reinforce the table).
