Google SCHOLAR is a subset of the larger Google search engine. It searches only for articles from mostly scholarly sources where the holder of the copyright has allowed internet access.
There is a new scam in academic publishing, sometimes referred to as "predatory journals." These are made-up, online journals that charge authors to publish their articles, but the journals do not have legitimate peer-review, and will publish anything for a price. Often these journal names are closely related to the names of legitimate journals, so be careful. Google Scholar does not have a filter to screen out these "con-job" journals.
Here at KU, the librarians have configured Google Scholar to work with some of the library databases to pull in the PDF of articles you have a paid subscription for as a student here. To take advantage of this "extra", you need to use a special link. You can get it by going to the A-Z Database link and selecting Google Scholar from that page, or use this link: https://library.kutztown.edu/googlescholar
Use Google’s advanced searches to limit your results to more reliable domains (e.g. .gov and .edu).
