Presentation delivered at "Is There An App For That?" - a CPD25 event held in London on 25th July 2014. The presentation looks at how people interact with the internet, the popularity of certain tools and how I am currently exploring their suitability and potential as tools for a subject library in Higher Education. http://www.cpd25.ac.uk/events/social-media-event-event-ref-tg3soc/
