here an image of my bibliography.

enter image description here

As per the image, LaTeX makes an extra entry in my bibliography. Note that I do not have this references in my references.bib, nor do I have any references labelled 1 in the text itself.

Here's my preamble, if it helps:


        \bfseries \ackname
          {\bfseries \ackname\vspace{-.5em}\vspace{\z@}}%




frame = single, 

Here's an example of an entry in my references.bib

author = {Robert I. Kabacoff},
title = {About Quick-R},
year = {2012},
url = {http://www.statmethods.net/},

author = {Stack Exchange Inc},
title = {Welcome to Stack Overflow},
year = {2014},
url = {http://stackoverflow.com/about},

    Please add a minimal working example (MWE) that illustrates your problem. It will be much easier for us to reproduce your situation and find out what the issue is when we see compilable code, starting with \documentclass{...} and ending with \end{document}. – lockstep Jan 30 '14 at 9:05
  • Whats in your references.bib? – Chris Jan 30 '14 at 9:16

    Your example doesn't help to reproduce the issue. – karlkoeller Jan 30 '14 at 12:05

    @WetFeet An obvious error to correct is that you miss a trailing comma at line 44 of references.bib. I'd also change all “curly apostrophes” into ' in the .bib file. Finally, it could be a version problem: ShareLaTeX uses biblatex version 1.7, which is quite outdated. – egreg Jan 30 '14 at 14:33

    This question appears to be off-topic because it is about an input error that was fixed in the comments. – moewe Jan 30 '14 at 19:13
