title: pdf viewer for reading scientific papers
body: <p>I am looking for a way to improve my productivity reading scientific papers. One big improvement would be if I would not have to jump back and forth between the written text, the references section and google to get an idea of what a referenced paper is about. My example:</p>
  
  <ul>
  <li>Excerpt of text from page 2:
  "Explicit solvent models arguably provide the most detailed and complete description of hydration phenomena[1]."</li>
  <li>Scroll all the way down to the reference section (page 24) to find:
  "[1] Levy RM, Gallicchio E. Annu Rev Phys Chem 1998;49:531–67. [PubMed: 9933909]"</li>
  <li>Copy the reference and paste it into google to retrieve the title:
  "Computer simulations with explicit solvent: recent progress in the thermodynamic decomposition of free energies and in modeling electrostatic effects." and the abstract</li>
  <li>Return to pdf, get back to the last position in the text and continue reading until the next interesting reference comes up and repeat this process</li>
  </ul>
  
  <p>I used texpad(<a href="https://www.texpad.com/" rel="nofollow noreferrer">https://www.texpad.com/</a>) for a while and I enjoyed how I kept track of my references/citations. In texpad, after typing the keyword for cititing, you get shown a selection of entries in your bibliography that you could add and even abstract can be shown so that you really know what you are citing. So far I haven't found a pdf viewer that has any features for easily retrieving references.</p>
  
  <p>Is there anything out there that I am not aware of?</p>
