The original source of the images for Westergaard's Dhatupatha was from the scanned edition at Internet Archive of Radices Linguae Sanscritae by N.L. Westergaard (1841). Only the Dhatupatha portion of Westergaard's book is included in the display. The format of the images in 'radiceslinguaesa00westuoft_jp2.zip' has been adjusted to a smaller black and white 'jpg' format.
