Search Engines

I have used the following search engines to find publications:

• Google Scholar: Provides both a simple and an ‘Advanced Search’.
• IEEE Xplore ^TM: A database of scientific and technical content published by the IEEE (Institute of Electrical and Electronics Engineers) and partners.
• ScienceDirect: A database of scientific, technical and medical research
• Scopus: A database of peer-reviewed research literature
• PubMed: A database of medical research, including much biomedical engineering research
