Citation help in Access Engineering is different from that offered in Access Science. Once you've found a chapter you intend to cite, scroll to the bottom of the page. There you'll find a sample citation with author, chapter name, book title, publisher, date, and database name elements. Depending on the citation style, this is unlikely to be adequate: you'll have to edit the elements to fit the style you are using for your bibliography.
Clicking the EXPORT button will create an RIS file for the citation which can be loaded into a citation manager like RefWorks.
