Scientists collaborate a lot. The Web of Science tells you who all the coauthors are. Search on Dr. A (Type "Anandakrishnan S" into the author box of the search page). Notice that many of the entries list a few authors followed by "et al." (which stands for "et alia" and means "and others" in Latin). If you click on the blue title, you’ll see a list of all of the authors. So, who was Dr. A co-authoring with in 1995?
