The Chemistry Library, which is now located on the 2nd and 3rd floors of the Institute of Atomic and Molecular Science, Academia Sinica, was established in 1966. The library is financially supported by National Taiwan University and the Chemistry Promotion Center of the National Science and Technology Council (NSTC). In 2009, the study spaces, the circulation desk and the casual sofa area on the second floor were renovated in order to enhance a user-friendly environment. The Chemistry Library houses more than 20,000 books and 200 journals providing the most comprehensive chemical information service in Taiwan.
