• It is best practice to find the original source you find quoted in another source – for accuracy and to check that the meaning of the original has not been lost.
• Also known as a secondary source, they should only be used when you cannot retrieve a copy of the original source.
• In the text of your essay include the original’s author and date and write “quoted in” and use the secondary author last name year.
• List the secondary source in the Reference List  - ie the one you found the quote/idea etc in.
• Sometimes if what you are looking at online is made available by an institution holding the originals – like art works, manuscripts and diaries etc – they can be considered as primary sources so you would reference them as that – use formatting advice according to the type of source you are using.
• If source is online, add URL.
