O"Reilly is known for its strong Unix titles, from Learning the UNIX Operating System to Unix in a Nutshell. Here, O"Reilly gathers its Unix titles on one conveniently searchable CD-Rom, which will be great news for those who prefer online help to printed pages. The six books included are Learning the UNIX Operating System, 4th Edition, Unix in a Nutshell, Unix Power Tools, sed & awk, Learning the Korn Shell, and Learning the Vi Editor, 6th Edition. The books are formatted in HTML, fully searchable and cross-referenced, and can be read by any Web browser. There"s a handy master index for the entire library--and a bonus copy of Unix in a Nutshell, 3rd Edition for those who miss the feel of paper.--Acton Lane
