This online text of the Rigveda derives from the highly important Rig Veda: a Metrically Restored Text, by Barend A. van Nooten and Gary B. Holland, published in 1994 by Harvard University Press. The text here is based on the van Nooten & Holland electronic version (itself derived from the much earlier UT Linguistics Research Center electronic text), which was issued on a 3.5" diskette together with the printed book.
