This devanagari version of Rigveda in ITRANS format files was originally created by Avinash Sathayeand (late) Shashi Sathaye based on Harvard Oriental Series volume 50 by van Nooten and Gary Holland.  

They were reprocessed from Original in final form by Detlef Eichler with additional corrections. See Detlef's site http://www.detlef108.de/Rigveda.htm for other details and formats. Contact Detlef Eicher: detlefeichler@googlemail.com

Itranslator 2003 from Omkarananda Ashram was used for converting the files to HTML web pages in Unicode format.

Avinash Chpade's ITRANS was used to convert the files to devanagari postscript and PDF formats. (See description of formats and viewers)
