It's too hard to just 'jump into ArcGIS, and the book works well as a tutorial - better than what's on line for free - so it might still be worth buying. But it really only gives you just a once over lightly of the software, cookbook style, and doesn't cover everything. The book works poorly as a reference to help you with particular questions as they come up. It only has a skimpy four page index, includes very little in the way of background or discussion of subject material. ArcGIS has moved to version 2.0 since this book was published in 2016, but that didn't seem to present many problems. I noticed very few instances in which the old screen shots didn't look like the current screen. But at $54, it should be comprehensive and up-to-date.
