My Library
The Official Mobile App

Q1. What is “My Library”?
A1. “My Library” is the official mobile application developed for Hong Kong Public Libraries (HKPL) by the Leisure and Cultural Services Department (LCSD). It provides a safe and convenient channel for users to access library services in the mobile world at any time and any place.

Q2. What is the difference between the App and the online library catalogue?
A2. The App provides some core features of the online library catalogue, such as searching, reserving and renewing library materials, in a most convenient manner available on mobile devices. It will also offer other new features like personalized notification services and finding nearby libraries via GPS*.

Q3. Do I need to sign in with a valid library account to use the App?
A3.  You need to sign in your own library account for renewal, reservation or managing My Lists. However, you can still search library catalogue or find library information without signing in.

Q4. What is the difference if I turn on “Auto login”?
A4. If you enable “Auto login”, your account information, i.e. library card number and password, would be saved in the App for future sign in automatically. You can also enjoy the personalized alert services available on the App. Users are however reminded to keep safe custody of their mobile phones/devices if they turn on this function, otherwise, there may be potential leak of personal information.

Q5. How do the personalized alert services work on my mobile devices?
A5. The App supports the reception of personalized alert through the Push Notification Service provided by Apple Inc., Google Inc. and Huawei Ltd. The alert messages will be delivered to your phone/device even when the App is closed. You can turn on/off different types of alert through the notification setting in the menu of the App.

Q6. Why is there only "Library News" setting shown in the "Notification" page?
A6. You need to enable the 'Auto login' function in order to receive other personalized notifications from library, including 1) Due Date, 2) Overdue , 3) Pick-up and 4) Renewal Block Alert. You should click 'Sign In' again to re-enter your library account information and enable the 'Auto login' function.

Q7. What is “Renewal Block Alert”?
A7. If your borrowed item is reserved by other readers that may lead to denial of renewal, an alert will be sent to you 3 days prior to the item due date on daily basis. Since the status of reservation will change frequently from time to time, this alert is for reference only. Even if no alert is received, it does not guarantee the success of renewal when you make the request.

Q8. What is “Email Alert”? How to activate this service?
A8. You need to enable the "Auto login" function in order to register the App's "Email Alert" service. A simple email alert will be delivered to your registered email address one day in advance and on the due date of your borrowed library materials.

Q9. What is the correlation between “Email Alert” and the general Library Email Notification Service?
A9. During the registration of the App's "Email Alert" service, you may also enable the general Library Email Notification Service simultaneously, or update your registered email address in the library system as well.

Q10. What is "Scan Search"?
A10. The App can use the camera function of your mobile devices to scan the International Standard Book Number of a book (ISBN barcode printed on the back cover), in order to search if the book is already in stock of public libraries or not. User should place closely and target the camera len on the ISBN barcode for scanning.

Q11. What are the device requirements for using the App?

Q12. Why do I need to download “Library info file” and “Library map file” separately?

Q13. What is the purpose of share function available on the App?
A13. The function allows sharing the link of individual library item onto other social sharing platforms or messaging tools, including e-mail, Facebook, WhatsApp, Twitter, Weibo, etc., but no other personal data will be released at the same time.
