Sources with missing details (e.g. no author / editor or no date)
Answer
Evaluating sources and then choosing the best ones to help you make your arguments is part of good academic practice.
If a source does not reveal who made it or when it was made, you should carefully think about why this is the case, and decide whether the source is really suitable for use in an academic assignment. If you still decide to include it then use the following guidelines:
No author or editor
Authors and editors can be people or organisations. If neither is given, you can use the source title or URL in your in-text citation instead. You should not use 'Anon' in either your in-text citations or your reference list in Newman Harvard.
Examples
Using an anonymous source in an in-text citation
A broadside proclaimed it "the greatest number of spectators ever assembled for such an occasion" (Execution of the Mannings, 1849).

Note how the name of the source has 'jumped' over the date to take the place of the author's name, and matches the in-text citation.
No date
Look carefully for anything that shows when the source was made. On websites, this can be at the very bottom of the page, and on PDFs, you can sometimes find it on the back cover. If there is a copyright statement for the source (e.g. ‘© 2016’), you may use this as the date if no other date is present.
If you still cannot find a date, use the phrase ‘no date’ (without single quotations marks) in both your in-text citation and reference list.
Examples
Using 'no date' in an in-text citation
...the remains of a Victorian funicular railway (National Trust, no date).
