|Oxford Reference Online, Preview Citation|
Citation previews are available for MLA, APA, and Chicago styles. Simply highlight the style you want and the citation will appear to cut-and-paste. Be aware that you may have to insert the proper indents.
The format option allows you to create a file that you can import into RefWorks (among other citation managers): unfortunately, the extracted data is limited, lacking even the details generated with the preview citation, which you may prefer to use.
