Title: Information for beginners only
Review: If you know nothing about Linux, little about computers and want info on the caldera distribution then this book is an okay starter. But it will not give you enough details to be the source you rely on when running/installing Linux. Not quite three months after purchasing, my copy of the Idiot's Guide looks brand new while my O'Reilly Linux books are painfully dog-eared.
