The contents of this book would better be found in technical documents such as user guides, architecture guides, and admin guides. That some reviewers report that this may be the only place to find some of this information says more about the paucity of good IBM documentation (or perhaps just the poor organisation of the IBM portal support site) than about the quality of the book.This book is fairly limited to the "To save your data, click 'save'" brand of instructions (I thought Microsoft owned the patent on this technique?). Since many many portal configuration pages are self-explanatory, much of this instruction is wasted. And aside from a brief foray into Portlet development, which is a not-too-bad treatment for a neophyte, there is nothing for a developer.Finally, the name is misleading. Certainly, there is nothing in this book that could possibly lead to "mastery" of the IBM WebSphere Portal.Don't waste your money.
