The present concordance is a revised, updated, improved (technique-wise and otherwise) and enlarged DevanEgrI version of Bloomfield's famous Vedic Concordance. It is a great reference work on the Vedas comprising of an alphabetic pEda (quarter part) index of Vedic Mantras involving 120 Vedic texts. Following salient features have made the present edition more significant and valuable: The present concordance being in Devanagari script would give the readers the taste of the actual Mantra-pEdas of the Vedic texts. It would also help the readers to understand the Vedic Mantras in a more easy and lucid manner. It contains the correct alphabetical order of various entries from the point of Devanagari orthographic system wherever Bloomfield failed to maintain. Though Bloomfield tried his best to represent the Vedic lores in a most perfect manner through Roman letters by applying diacritical marks, still nasal sounds, supra segmental sounds like jihvamooleeya and upadhmaneeya sounds could not be represented as perfectly as they should have been. Bloomfield could not distinguish between many Sanskrit sounds represented in devanagari script through his diacritical system. Moreover the diacritical system adopted by him has become outdated these days. Under the circumstances, a new student trained in the current system will find lot of difficulties to make out the century's old system adopted and applied by him. So, the present author thought it appropriate and justified to present the Vedic concordance in the Devanagari script in an updated, revised and improved manner. We are pleased to announce that the much awaited fourth vol. has finally seen the light of the day. It is hoped that this complete four vol. work will be of great significance to all serious researchers of the Vedas. The author had to toil hard to make it palatable and as perfect as possible, still the mistakes of proof here and there cannot be ruled out.
