Three libraries that I know of that use social networking to meet their goals are Hong Kong Public Library, Hong Kong Baptist University Libraries and Hong Kong University Libraries.

In investigating these libraries I have developed a list of reasons why libraries should be on social media:

• Promotion and market reasons, many forms of these three libraries use social media for this purpose, as a result, they are exposed to hundreds of current and potential members to share their offer.
• Educational program opportunities, which provide three libraries electronic tutorials and publicity through their YouTube page. This use of social media in order to make the library service extends beyond their physical libraries, and provide more services than they might otherwise be able to, due to the physical capacity constraints, budget and time of limited.
• Social media is a way to further support services already in place. Online chat option, web pages and blog discussions backing review these libraries are meant to prove that they can assist the customer and service issues to a wider audience and more effective. In the reviewer’s staff use Facebook, allows members to post comments and share how usually provided by the service staff in the library can share a further example, faster access to more members.
• Using social media tools, operating in the enterprise, it is also a valuable resource to help the library. Tools such as WhatsApp, Facebook and Google+ are among internal staff, and to reach a wider audience of potential new and effective way employees communicate quickly and effectively.
• In order to remain relevant member who is getting the time difference, or who may not live physical access capabilities. By using social media libraries and the services provided are not so easy to be forgotten or not used. There is the emergence of a social media mean greatly increased the accessibility of members.
