Developed by the Centre for Sign Linguistics and Deaf Studies of CUHK, the "Online Library" is divided into 4 sections: "Baby Sign Language", "The Chinese Reader Series", "English Books" and "I Can Read (我自己會讀)". With up to 3092 videos, the website provides a learning and supporting platform for deaf and hearing students, parents and teachers. It consists of a wide range of topics, including vocabulary for daily life and basic grammar for Hong Kong sign language. The "Baby Sign Language" section is now open to public.
Participants of the FS2 may apply for an online account to access other sections.
