Each Google Scholar search result represents a body of scholarly work. This may include one or more related articles, or even multiple versions of one article. For example, a search result may consist of a group of articles including a preprint, a conference article, a （Ａ） , and an anthology article, all of which are associated with a single research effort. Grouping these articles allows us to more accurately measure the impact of research and to better present the different research efforts in an area.
