Emerald journals (engineering, applied science)
Advanced Search will find references in full text using the “all fields” search. Also, when you look at a journal article within Emerald, click on HTML version and above the information about the journal article you will see something that looks like: "Downloads: The fulltext of this document has been downloaded 1159 times since 2006." While this is not the number of times it has been "cited," it does give some indication of how often that article has been viewed. Emerald also provides usage data for specific articles "on request" - contact them and ask. They usually provide number of downloads per year for the article - and comparative data for other articles within the same journal.
