 ***PapersCited*** is a small Python program designed to help you with **writing and reviewing reference lists** in your scientific articles. It reads through a document of your choice and takes a note every time something is cited. At the end, it writes all those citations in an Excel file in alphabetical order, omitting duplicate entries.
