Publisher

• Do not confuse the publisher and the printer.
• Do not include unnecessary and unwieldy parts of the publisher's name, such as & co., ltd., press, & associates etc.
• Some examples:

  Phaidon (NOT Phaidon Press Limited)
  Longman
  Penguin
  HAUM
  Methuen
  Nasou
  Van Nostrand
  McGraw-Hill
  Routledge & Kegan Paul (note the use of the ampersand "&")

• If no publisher can be found, use s.n. (sine nomine). [Use italics for the Harvard method].
• NB. University presses: note that there is a difference between a work published by Oxford University Press or by Oxford University.
• NB. Publishers are not always commercial undertakings. They may be government or corporate bodies (e.g. UNESCO, World Health Organisation, Organisation for African Unity, African National Congress, etc.).
