Reference managers are great tools to organise citations for any type of research, while also helping when it is time to reference your work. These services keep the metadata of your citations, and you can choose the reference style you want it to use. For example, if you write an article for a publication that requires you to use the Author-Date citation system, but you are familiar with Non-superscripted Number, you can use the reference manager to change the formatting of the references quickly and easily.
