Teach Yourself English

Summary:
This is a very thorough Esperanto book; however, I have found a few minor typos like the "hat" being left off a letter where it definitely should be, and Esperanto titles of Mr., Mrs., and Miss (Sr-o, S-ino, and F-ino) are sometimes capitalized and sometimes not (and I don't mean just at the beginning of a sentence), but these should not present the student with any problems as they are very minor typos, and even the student can readily see that.
