When to use direct quotations
As a general rule, paraphrasing (rewording a passage) and summarizing are the best techniques to incorporate information from other sources in your work. Direct quotations (word-for-word extracts from a source).should be used sparingly, because the paper or thesis you are writing is supposed to be your original work.
Use direct quotations rather than paraphrasing:
When quoting directly, you must provide – in addition to author and publication year – a specific locator (such as a page number) that directs the reader to the specific location of the quoted text.
For works with page numbers, use "p." (e.g., p. 321) to indicate a single page; use "pp." (e.g., pp. 145–146) if the passage appears on two pages. Separate page numbers with an en dash (–).
For works without page numbers, such as web pages, some e-books, and (audio)visual works, direct the reader to the quoted text using a different locator. What locators you can use is discussed in Subsection 2.3: Textual works without page numbers and Subsection 2.4: (Audio)visual works.
