This paper presents the results of a research conducted on seven search engines - Google, Bing, Yahoo, Ask, Baidu, Dogpile and DuckDuckgo for retrieving scholarly articles using Library and Information Science related search terms. The search engines are evaluated by taking the first twenty results pertaining to 'scholarly articles' for estimation of precision, recall and F-measure. It shows that Baidu is most comprehensive in retrieving 'scholarly articles' followed by Google and Dogpile. It also reveals that all search engines (except Ask and Dogpile) perform well on structured queries while Ask and Dogpile performs better on unstructured queries.
