Articles provide information on very specific, narrow topics. The Library purchases article databases so you may access articles for your topic – for free. Researchers use them when they need:
Journals consist of articles written by scholars and researchers, reporting in detail on their original research, and "peer reviewed" by other experts before they’re published. Most are published by professional or academic organizations, for specialists in that field.
Journals are published regularly, like magazines, but most magazine articles provide more basic information, and are written for the average person.
IEEE Xplore is the full-text database of Institute of Electrical and Electronics Engineers (IEEE) and the Institution of Engineering and Technology (IET) publications, including publications from predecessors such as IEE (Institution of Electrical Engineers); IRE (Institute of Radio Engineers); and AIAA (American Institute of Electrical Engineers). It is listed on Databases A to Z under the category "Find Ariticles."
