What is Reddit's opinion of Handbook of Rocks, Minerals, and Gemstones?

From 3.5 billion Reddit comments

HEY! I found a Nat Geo magazine that might work:

A good mineral field guide is always a good thing too. They're usually easy to read and have only the most common minerals found on the Earth's surface. Something your nephew can grow into and use for years to come. This is one of my favorites and the one I take in the field. It has basics on different rock types and all sorts of minerals with pictures of what they'll actually look like on the ground (as opposed to the darn Smithsonian worthy samples that are ultra rare).
