Most databases provide sample citations drawn from standard templates, in many of the styles demonstrated in this guide. Citation Management Software and websites (EndNote, Zotero, Mendeley) and generators such as Chegg and EasyBib also will auto-generate citations. In many cases the citations may have mistakes in formatting. In addition, artificial intelligence tools using Large Language Models (LLM) such as ChatGPT can generate false citations using legitimate author names and journal titles.
Always double-check your citations for authenticity and accuracy!
