In general, it is recommended to read the original source or item being quoted, rather than relying on another source.
Where this is not possible, and one must rely on a "secondary source," then these are the available guidelines on how to cite it.
Reference: #. Author Last name Initials. Title. Edition. Place of publication: Publisher; Year of publication. pagination [i.e. how many pages are in the item].
25. Frogmantan, RW, Lewis, CS. The unusual case of how DNA was discovered. Dublin: Millar Press; 2007 641 p.
Use a superscript number (like this: ¹) in the text at the place where you are indicating that you are citing from a source.
Originally Crick and Watson, cited in Frogmantan and Lewis25, identified DNA. This was done by putting an onion in a juice machine and extracting a single onion cell.
Note: Vancouver Style does not have explicit guidelines for secondary sources. These rules have been adapted with kind permission of the University of York. See their Online Guide for full details.
