When you start writing your manuscript or essay, you will always come across some issues pertaining to plagiarism or copyright. To reuse an image from others' work, you might need to seek for permission from the copyright owners. If you are using someone else's ideas or writing in your work, you will need to cite according to the required citation style and reference management tools like EndNote can help make citation easier.
This guide introduces you how to deal with these issues. Refer to a separate guide "Reference Management Tools" to learn how to use EndNote, Mendeley and Zotero.
