EndNote is a commercial reference management software package, used to manage bibliographies and references when writing papers and articles. Many databases allow you to export citations directly to EndNote. Users need to set up a free account to store their references.
Keep careful research notes and keep track of citations and where your information comes from.
Copy and paste judiciously
Remember that most of the words you are using should be yours. Quotes from sources should be used to bolster your ideas.
If you paraphrase or quote, you need to cite. Other people's ideas need to be credited as well as their quoted words.
