title: Can I remove the labels from the bibliography, while keeping them in citations?
body: <p>I'm writing the bibliography of my report with <em>thebibliography</em> because I don't need a BibTeX database (or I don't have the time for learn how to customize or write a style).</p>
  
  <p>The optional argument <code>[label]</code> specifies how the reference will be cited in my main text. Here's my reference definition:</p>
  
  <pre><code>\bibitem[PNUD1996]{PNUD1996} PNUD. Desarrollo Humano en Chile 1996. Santiago: PNUD, 1996.
  </code></pre>
  
  <p>If I write: <code>in \cite{PNUD1996}.</code> it produces:</p>
  
  <blockquote>
    <p>in [PNUD1996].</p>
  </blockquote>
  
  <p>But the label also appears in the bibliography:</p>
  
  <blockquote>
    <p>[PNUD1996] PNUD. Desarrollo Humano en Chile 1996. Santiago: PNUD, 1996.</p>
  </blockquote>
  
  <p>Can I remove the label from the bibliography and keep it in the reference? I mean, to get:</p>
  
  <blockquote>
    <p>in [PNUD1996].</p>
  </blockquote>
  
  <p>and</p>
  
  <blockquote>
    <p>PNUD. Desarrollo Humano en Chile 1996. Santiago: PNUD, 1996.</p>
  </blockquote>
