Reports can be written by researchers and published by a university or other research institute. They can also be written and published by authorities or other organizations, and these reports can have personal authors or be authored on behalf of the organization. In the latter case, the organization is the author.
Research reports are stated in the same ways as books but with the added possibility to also state any name and number of the report series. The name and number of the series are usually found on the front or back of the publication, or on the title page inside the report.
Reports can be published in printed form but are usually also, or only, published in digital form online.

If an organization has an established acronym (abbreviation), you write the full name the first time you cite the source, include the acronym within parentheses, and use only the acronym the subsequent times you cite the same source. Note that if you write the full name within parenthesis, you write the acronym within square brackets, but if you write the full name in the running text you state the acronym within ordinary parentheses.
