Personal communications

Important Note: Check with your lecturer first to see if these type of resources are acceptable for use.

Personal communications usually take the form of a conversation, a letter, or an email.  They are generally unpublished and not usually acceptable as a reference.  However if their content is very important in the context of your work, they may included.  It is recommended that permission be sought from the source or party to the conversation if you wish to include quotes in your text.

Personal communications are cited within the text but are not included in the reference list, unless they are publically available in an archive or repository.

Personal communication in the text of your document should include:

  • Date of communication
  • Type of communication - oral, written or email (include email address)
  • If appropriate,  the affiliation of the correspondant to a University or organization.
