Quoting means rendering word for word what somebody has written or said. Quotes are mainly used when you want to refer to a wording which is striking or ground-breaking, or if you risk altering the meaning by rephrasing it. You can also use quotes when you present a statement which you question and want to discuss. In most other cases it is better to paraphrase the content.
To separate quotes from the rest of the text they are either marked as run-in quotations or block quotations. If the quote only consists of a few words or a single sentence it is suitable to make a run-in quotation which is marked with quotation marks. Run-in quotations are therefore embedded in the text. If the text you are quoting consists of several sentences you make a block quotation instead. This is placed as a separate block without quotation marks. It is marked with an indent in the left and possibly also the right margin and can have a smaller font size and line spacing.
With both run-in quotations and block quotations you should state the source with a text reference in direct connection to the quote and with a full reference in the list of references. In addition, text references with quotes should always contain a page reference.
