Multi-disciplinary database of peer-reviewed research literature.
Please note: there are problems with the Scopus service. Full-text links and exports to some citation managers are not working. A workaround to get the full text is to copy and paste the article title into ONE SEARCH on the library home page, and you'll be able to access the full text.
This search engine allows you to search government resources including NIH, medical societies, commercial databases and patents. It may not be as in depth as PubMed, but may hit other sources on the web
