Citing your sources is not only a way of avoiding plagiarism, but also a way of showing respect and gratitude to the original authors and acknowledging their contributions to your speech. To do this properly, you should choose a citation style that is appropriate for your field, discipline, or occasion. This could be APA, MLA, Chicago, or Harvard. Additionally, you should provide in-text citations whenever you quote, paraphrase, or summarize a source in your speech. This usually includes the author's name and the year of publication, and sometimes the page number or the URL. At the end of your speech or on a separate handout, you should also provide a list of references or a bibliography with full details of your sources such as titles, publishers, dates, and URLs. When selecting sources for your speech, be sure to use credible and reputable ones such as peer-reviewed journals, books, government websites, and reputable news outlets. Avoid unreliable sources that are outdated, biased, or anonymous.
