Title: Unreadable
Review: I picked this up in a remainder bookshop, and I can see why. The useful content could be summarised in two sheets of A4. It is littered with diagrams, each virtually identical to the last. The text, in explaining diagrams, refers to labels that do not exist. It appears not to have been proof-read (revised paragraphs can appear after the version they were presumably intended to replace). The first 200 pages are irrelevant, offering vague generalisations repeated ad nauseam. Then SANs are introduced and treated dismissively. Altogether the worst book on any topic that I've ever read.
