Google has released another useful tool. Google Scholar provides a search system for professional journals, conference papers, and other scholarly works. You cannot access the full-text articles, but this service can be useful for locating references. For example, I sometimes need to check a citation and this service will identify the citation in other reference lists.
Google Scholar also provides a way for scholars to see who is referencing their work. Just for kicks, I entered a couple of words from a paper I published based on my dissertation (in 1976) and my last name. Sure enough, the paper was referenced in 2002. This capability may not make sense to most Internet users, but researchers do like to know who is referencing them.
