This is not a textbook¶
Although it's formatted a bit like a textbook, if you are trying to actually learn Korean yourself, this is probably not what you should be reading, because
- It's written by an American who doesn't actually know any Korean.
- It doesn't cover vocabulary or Hangul.
- It's excessively academic compared to many practical texts.
Overall I would say this is more like me telling my friends about what I learned rather than me writing anything for an actual Korean student.
