Japanese Text Initiative 
Ebook collection of web texts of classical Japanese literature in Japanese characters. Contains only out-of-copyright editions, meant to serve as supplements to current scholarly editions for quick word-searching. In a few cases, e-texts have been newly edited for this website, and so can be considered authoritative texts. Examples can be found in the British Poetry category at the E-Text Center, as well as Kokinshu.
