There is no agreement or clear-cut criteria on how much plagiarism is allowed in a paper. According to the standard, a text resemblance of less than 15% is regarded acceptable by journals, but a similarity of more than 25% is considered a high degree of plagiarism. Some experts say that even a very small amount of plagiarism can lead to rejection of the paper. The best way to avoid plagiarism is to do your own research and write your own papers from scratch. However, if you do use other people's ideas in your work, it is important to give them proper credit. This can be done in several ways: by citing the source(s) in the text or using footnotes or endnotes. A citation is a reference to the source of information or idea used in your paper. Using citations makes your work more accurate as well as credible. Citing sources also shows that you have taken the time to check your facts and support your arguments with evidence. Endnotes are notes at the bottom of pages. They should not be referred to during the writing of the paper or outline. Endnotes are useful for recording detailed explanations or references which cannot fit into the body of the text. The use of endnotes helps prevent plagiarism since these notes are specific to the paper and not available elsewhere online. Footnotes are notes at the bottom of pages.
