The Andalusian Public Health System Virtual Library conducted a survey to evaluate the capabilities and knowledge of their users regarding social networks and Web 2.0 tools. The survey received 518 responses from potential users. The results showed that while 68% of users edit their own blogs, only 49% use professional social networks. Most users tend to share and comment on content rather than create their own. A majority of 52.6% use mobile devices to access the internet. The library concluded that increasing mobile access and participation in social networks could improve communication and interaction with users.
