Dear Patrons,
Since you can practically find everything online these days, it would be nice to make full use of your time on positive and beneficial online learning resources. For your reference, the Library selected several top learning sites and loosely collected them into 3 categories: general, arts, and science.
Most sites recommended use the freemium model with some contents accessible without charge. The rest are totally free. You may find actual university curriculum course materials as well as very general non-academic resources. Most sites are available in English or multi languages. A few sites only available in Chinese will also be instructed in Chinese below.
