Hey Fatema,

The Vancouver method is a simple way to show where information in a scientific research paper comes from. When an author mentions a fact from another study, they serially put a small number next to it as they continue to cite others papers (e.g., [1], [2] or as superscripts). At the end of the paper, there's a list with the same numbers that gives details about each study, like who wrote it and where it was published. This makes it easy for readers to look up the sources and see where the information came from.

You can use Mendeley to access the features for easy scientific writing and citation of articles.
