Many of us use Google to search the web for personal research and library resources for scholarly publications. Sometimes, however, it’s not clear whether what we need will be on the web or in scholarly literature. I’d like to point out some nice search engines for specific types of information that combine the ease of Google with the specialization of a library database. These tools could help you make sense of the web.
