3. Review and resolve issues

Reviewing every similarity is important to make sure you have not committed unintentional plagiarism. Follow the steps below to review and resolve all issues.

1. Is it actually plagiarism?

Not every similarity is plagiarism. Ask yourself:

  • Are these my own words and ideas?

If the answer to this question is “Yes,” then this similarity probably does not constitute plagiarism.

If the answer is “no,” and you have copied or adapted someone else’s words or ideas, you should correctly credit the source.

2. Paraphrase or quote

Using someone else’s words or ideas is fine, but you need to credit the source. You should either quote or paraphrase the original text.

Paraphrasing means formulating someone else’s ideas in your own words, without changing the meaning of the original text. Even when you paraphrase, you should cite the source.

Quoting means copying someone else’s words without changing them. A quote is placed in quotation marks and accompanied by an in-text citation.

Frequently asked questions

When should I use the Own Sources Checker instead of the Scribbr Plagiarism Checker?

The Scribbr Plagiarism Checker compares your document against the largest plagiarism database in the world. It will detect any similarities with documents in that database.

However, you might be unsure if all of the sources you used are in that database – for example, because some of your sources are unpublished. In this case, you can make use of our Own Sources Checker. Here you can add all the sources you want to a private database and compare them with your own document.

How many sources can I add to the Own Sources Checker?

You can add up to 25 sources at a time to the Own Sources Checker. If you want to add other sources as well, you need to remove others first.

How can I add internet sources?

Here’s how it works:

  1. Browse to your internet source and select the text. Right click and choose “Copy”.
  2. Head over to the Own Sources Checker and click the “Paste text” button.
  3. Right click on the text area and choose paste.
  4. Your source text now appears in the text area.
  5. Click “Add source” to upload your source.

Will my sources/document be stored in a (shared) database?
