The IIT Bombay corpus was the largest public English-Hindi parallel corpus when published, is documented source by source, and has been the English-Hindi data for the Workshop on Asian Translation shared tasks. Its roughly one and a half million sentence pairs cover a single language pair, far from the billions of pairs in the largest parallel collections, and the Bharat Parallel Corpus Collection spans twenty-two Indian languages with far more pairs.
