Q: Is it plagiarism if I look at summaries from different sources, put sentences together and also add some of mine in?

Thank you for your question. Using someone else’s written information with some changes in those sentences in your own text can amount to plagiarism, even if the words differ, because the original idea remains the same. To avoid plagiarism, you must give credit whenever you quote another person's written or verbal sentences; paraphrase/modify another person's spoken or written words, borrow ideas theories, ideas, opinions, etc. or use previously published historical, statistical, or scientific facts or data. To counter this problem, please keep track of the sources you consult, quote from your sources (and add your own ideas), add the relevant reference to the original author/source in the in-text citations and in the list of references. It would also help to get a professional plagiarism check report before submitting your manuscript.
