Title: Outdated information
Product review: Getting this book was a big mistake. It seems like this book was going to have a lot of information but it does not. The print is very large and there are many large empty spaces on many pages. The content is completely out-of-date. This book was first published in 1985 and most of the content is from 1985. The photos in the book are blown up jpegs stolen from web sites (hence the different photo credits on EVERY image). It still refers to servers as "mainframes". This book basically tells you about the different kinds of bar codes and how they are read. And THAT IS IT. There is NOTHING about software or modern hardware. There is nothing on creating a database. There is nothing about wireless technologies. My message: AVOID THIS BOOK.
