Citing specialised software

  • References are not necessary for standard software and programming languages, such as Microsoft Word, Java, Adobe Photoshop and SPSS. In the text, give the proper name of the software, along with the version number – e.g. IBM SPSS Statistics for Windows, Version 21.0.
  • Do provide reference entries for specialised software or computer programmes with limited distribution.
  • Do not italicise the title of software.
  • The rightsholder may be an individual, a group or a company.
  • If an individual has proprietary rights to the software, name them as the author; otherwise, treat such references as un-authored works.
  • The date is the year the version you used was released, even though previous versions may have been released in different years.
