Quoting vs paraphrasing

Quoting reproduces a source’s exact words in quotation marks; paraphrasing restates an idea in your own words. Both — like summarising — always require a citation.

The step most authors miss

Doing CRediT right? Don’t stop at the statement.

A CRediT statement credits you inside one paper. The recognition CRediT was built for happens when those roles are tied to you, persistently. Sign in with your ORCID — free — and claim your CRediT contributions on casrai.org, the home of the standard. They become a verified, portable part of your identity, not a line that disappears into one PDF.

Free: claim your contributions, then export a journal-ready CRediT statement, schema.org structured data, JATS XML, CSV or BibTeX — and preview your public profile. A membership publishes that profile publicly and verifies the journals you serve.

Where summarising fits in

Summarising is the third way of drawing on a source, and it sits alongside quoting and paraphrasing. Where a paraphrase restates a specific passage at roughly its original length, a summary condenses a longer piece — a section, chapter or whole study — into a short statement of its main points, in your own words. Use it to give an overview or context rather than to convey a single detailed point. Like the other two, summarising requires a citation, because the ideas, however compressed, still come from the source. A well-judged piece of academic writing usually leans on paraphrase and summary, reserving direct quotation for the moments when the exact wording truly matters.

Common questions

FAQ

Do I need to cite a paraphrase and a summary, or only a quote?+

All three need a citation. Quoting, paraphrasing and summarising all draw their content from a source, so each must credit it — the citation acknowledges the idea, not just the wording. The only difference is that quotations also need quotation marks (or block formatting) around the exact words, whereas paraphrases and summaries do not.

When should I quote instead of paraphrase?+

Quote when the precise wording matters: a formal definition, a distinctive or memorable phrase, a contested or technical claim where rewording could distort meaning, or a passage you intend to analyse closely. For most other purposes, paraphrasing is better because it keeps the text in your own voice and demonstrates understanding. Quote sparingly so quotations support, rather than replace, your argument.

What is the difference between paraphrasing and summarising?+

Both restate a source in your own words, but at different scales. A paraphrase reworks a specific passage and is usually about the same length as the original. A summary condenses a longer source — a section or whole work — into its main points and is much shorter. You paraphrase to carry a particular point and summarise to give an overview; both require a citation.
