Many of our databases have this 
button, which searches for the full-text of the article in our collections. If we don't have it electronically, look for the "Request article scan" link in the "Get It" section.
In addition, try searching non-science databases that relate to your research topic. For example, if you are writing about the economics of technology in restaurants, first search a broad database like Expanded Academic Index and then search a subject specific database such as EconLit.
