One of the most often asked questions seems to be where one can buy or read the novel. Here, I'll post links where you can do so.

Moss Roberts(Pinyin)version:
http://www.amazon.com/Three-Kingdoms-Chine...18071567&sr=8-1

The Moss Roberts edition uses the more common translations of names that is used today, such as Cao Cao and Sun Quan. It also comes with a large number of notes and is widely regarded as one of, if not the best, translations.

C.H. Brewitt Taylor(Wade Giles) version:
http://www.amazon.com/Romance-Three-Kingdo...18071890&sr=8-2

The C.H. Brewitt Taylor edition uses the Wade Giles translation style, which is much more phonetic, like Ts'ao Ts'ao and Sun Chuan. It has a much more literary style, but more errors and no translation notes.

Online version:

An online version of the novel using the C.H. Brewitt Taylor translation with the Pinyin style names. Aside from the actual novel, the website offers a lot of information about it's writing, online notes for each paragraph, a large map of Three Kingdoms China, and a link to download the novel onto your PC.
