I want to read Rumiko Takahashi in English!

Rumiko Takahashi has had a huge effect on anime and manga; no less than three of her works have been hugely popular (Urusei Yatsura, Ranma 1/2, and InuYasha).

So, exactly how much of Rumiko Takahashi's manga is available in English?

Surprisingly, almost all of it is. A few volumes of her earlier works are getting a little hard to find, but at worst you'd need to buy a cheap used copy.
