social media and libraries 
Library advocacy is stronger and louder with the use of social media – attracting supporters to campaigns to save libraries or fix budget cuts, promote new products and services or raise awareness of libraries.
Social media is serious business. It has transformed the way many of us do our jobs and live our lives. It has blended the personal and the professional in a way that was as revolutionary as the introduction of the mobile phone. The merging of the two, with smart phones meeting the tools of social media has been another leap forward in the indispensable nature of social media.
Social media (and associated Web 2.0 tools) allows programs such as ours to exist, run by volunteers and using free tools that enable people to connect all over the globe.
libraries have not been left behind in the use of social media. librarians  present at virtual conferences, bring all participants together using virtual meeting software, connect with the global library community through twitter chats and use Storify to capture those twitter chats so anyone who missed out can see what was discussed in the meeting.
