# Citation Management Software

### What is citation management software?

> A reference manager supports researchers in performing three basic research steps: **searching, storing, and writing** \[...\]. It helps researchers find relevant literature, allows them to store papers and their bibliographic metadata in a personal database for later retrieval, and allows researchers to insert citations and references in a chosen citation style when writing a text.<sup>1</sup>

Citation managers can save researchers a lot of time, help reduce mistakes, and help avoid plagiarism. For those reasons, they are highly recommended.
