The official mobile application named “My Library” has been launched in Hong Kong to facilitate the mobile users to access public library services on anytime, anywhere basis. The app has been developed by Hong Kong Public Libraries (HKPL) for the Leisure and Cultural Services Department (LCSD), Hong Kong. The new app comes with some core features of the online library catalogue, such as searching, reserving and renewing library materials along with other features such as personalized notification services and finding nearby libraries (i.e.- address & contact information of libraries) via GPS. The new app comes with Auto login functionality and uses Push Notification Service provided by Apple Inc. or Google Inc. for the reception of personalized alerts. These messages include information on Due Date, Overdue, Pick-up and Renewal Block Alert, and are delivered on the users’ phone/device even when the app is closed. The new app also enables turning on/off different types of alert through the notification setting in the menu of the app. The app also features ability to scan the International Standard Book Number of a book (ISBN barcode) using the camera function of the mobile to check the existing stock of public libraries for the availability of a particular book. It also allows sharing the link of individual library items onto other social sharing platforms or messaging tools, including e-mail, Twitter, Facebook, WhatsApp, Weibo, etc.
