A colleague recently remarked that there were around 2,000 citation formats available in EndNote. One major area of weakness in all of the current citation systems has been the citation of audiovisual media, whether in physical, broadcast, or online forms.
Back in 2011, the British Universities Film & Video Council (BUFVC) and Royal Holloway College set up a group to address this issue, and ahead of publication of their recommendations in March next year, the BUFVC is asking for feedback on user experiences of citing audiovisual resources and what you would like to see covered by the guidelines. The online survey, open until 14th January 2013, is available on the BUFVC website, along with further information about the project.
