How to buy for english book in Seoul

I love reading books, especially English Book. It's one of my hobby and I would spend hours, in a book store. Longer, if it's free reading.

Currently, I am searching for this book:-

Interestingly, they even sell second hand book.
And also, they even have website which you can purchase via online.
