If you cannot find a year of publication, insert [no date] in the reference.
Example:
National Down Syndrome Society [no date] Associated medical conditions. Available from: http://www.ndss.org [Accessed 4 May 2019].
In-text citation: (National Down Syndrome Society, no date)
If there is no named author and no corporate author, start the reference with the title of the source.
Example:
A writer’s note-book (1946) Malvern: The Tantivy Press.
In-text citation: (A writer’s note-book, 1946)
If you want to cite a website which has no author or title, cite the website’s title. However, be very wary of citing web pages that have little information about the author and their credentials.
Example:
Occupational performance measurement issues and methodologies (2016) Available from: http://www.otdirect.co.uk/measure.html [Accessed 22 June 2019].
In-text citation: (Occupational performance measurement issues and methodologies, 2016)
When citing a direct quote, if there are no page numbers, use the paragraph no., chapter no. or the % (on an e-book reader) instead.
Example:
(Smith, 2018, para 4).
