The book takes a logical approach. First is a general introduction to the breadth of the topic. Then the book goes into mineral, how they form and their differences. Then it lists minerals. After that it discusses the common types of rocks, breaks those types down further. Finally it lists the types of rocks. There are pictures for the rock and minerals. At the end are tables to aid in identification. Finally, an index is present as well.

The inside cover boasts a retail price under two dollars which, even back in 1973 was inexpensive for the amount of information in the book. ( )
