The Tuanku Bainun Library (PTB) at the Universiti Pendidikan Sultan Idris (UPSI) campus in Perak, which will turn 100 next year, continues to be a resource centre for scholars, writers, linguists and well-known national figures.
PTB has a collection of over three million literary works, including e-journals and e-books (that can be accessed by researchers and the public). The library is the only department in UPSI that was inherited from the era of the Sultan Idris Training College (SITC) administration since 1922.
