== Accuracy of Harper reference == 

  You recently corrected a reference I included in the article (Harper et al., 2009) - thanks very much for this.  I found this article using Google Scholar and used the "cite" function to copy and paste the in-line reference. The Google Scholar citation is -  
 :Harper, G. S., Brownlee, A., Hall, T. E., Seymour, R., Lyons, R., & Ledwith, P. (2009). Global progress toward transgenic food animals: a survey of publicly available information. St. Lucia (Qld.): CSIRO Livestock Industries. Online verkrijgbaar van http://www. foodstandards. gov. au/_srcfiles/Transgenic% 20Livestock% 20Review% 20CSIRO% 20FI NAL% 2012Dec20031. pdf.

 I can understand why you changed the publisher as this is in the document, but I do not understand how you found the different publication date (2003 c.f. 2009).  The date is particularly important because I would probably not have used the source if I had known it was 12 years old rather than 6! (If anyone wishes to delete the source because of this, I will not complain.)  Please understand, I am not complaining here, I am simply trying to find out if other tools are out there for checking reference details, and perhaps we should be checking the details provided by Google Scholar.DrChrissy
