Quoted matter
Block quotations should be indented and separated from surrounding text by spacing: you do not need to use quotation marks. The text should formatted normally, not printed in italics.
Do not overuse excerpts from other works or from case studies. It is usually better to summarise their idea in one or two sentences. It is unfair to present the reader with a long series of quoted material with little explanation or description.
When it is important to quote in a foreign language, you should quote in the original and follow this directly (not in a note) with an English translation in brackets.
