The number of letters published by Indian scientists has remained constant during the three blocks. These letters were scattered in a large number of journals published from advanced countries of the world and India. The letters came from more than 1000 institutions located in different parts of the country. The highest number of letters was published in the discipline of medicine and the letters published in the field of chemistry had the highest Relative Citation Impact (RCI). [ABSTRACT FROM AUTHOR]
