There are undoubtedly many books on using social media technologies to market a service but few that cover several technologies in one guide. This step-by-step guide introduces different technologies and shows the reader how to make use of them to market a library service. The social media technologies covered include Facebook, wikis, video-sharing sites, Pinterest, Google+, Foursquare, blogs, QR codes and Twitter. It is unlikely that any library will want or need to use all of these tools and this guide equips the readers with the knowledge to select the ones that will work best in their library’s context and meet their user needs.
