I want to show only a part of my cited bibliography. In my MWE, I cited three references, but when calling my bibliography at the end of the document I just want to show the first reference of my bibliography. In other words, I need to cite three references and only display one of those three. I need this because it is an exposition and I need to talk about just a small part of the cited bibliography.
This is the code
\documentclass{beamer}
\usepackage{filecontents}
