Abstract Linking full-text proprietary databases with Google Scholar revealed three significant limitations in terms of precision (no subject heading search), transparency (no listing of information sources), and visibility (Google Scholar details are hard to find). Google Scholar is not a “one stop shopping” search engine that retrieves all relevant data from a library's licensed content. Despite these shortcomings, Google Scholar is a worthwhile search option for students, which may steer them away from Web resources, and towards the library's catalog and databases.
