The textbook used for my Minerology class. This is the first textbook I kept because I wanted thought the information would remain relevant, rather than the buyback price too low.
I use the simon and schuster book for a field guide in ny daypack. Super useful for reference.
A nice adult-level rocks and minerals guide with plenty of colored pictures. :D Something like this.
