The National Library of Public Information (NLPI) is one of the earliest public libraries in Taiwan, founded in 1923. Formerly known as the Taichung Prefecture Library, Taiwan Provincial Taichung Library, and National Taichung Library. The NLPI's new main library was open on June 3, 2012, and renamed to its current name on January 1, 2013. With citizens across the nation as its service targets, the NLPI is responsible for helping other public libraries throughout the country efficiently serve their users. It is also the first national-level digital public library in Taiwan.

Located on Wuqian S. Road in Taichung City South District, the main library has a total floor area of 41,797 m2, with five stories above ground and two stories underground. The NLPI has three branch libraries - Liming, Jingwu, and Zhongxing - and its services include the acquisition, organization, and holding of various physical materials and digital resources for citizens to read and pursue lifelong learning. It also provides age and target group segmented services, by combining physical and virtual service spaces.

With brand new reading modes, unique exploration routes, versatile recreational functions, and a comfortable environment for engaging in lifelong learning, the NLPI is a physical and digital field for reading, information retrieval, digital services, exhibitions, lectures, and training. It has also purchased the shared digital resources for nationwide public libraries. The NLPI aims to offer a library experience that promotes REAL (Reading, Exploring, recreAtion, and Learning) for all its users, to be the digital resource cloud center of all the public libraries, and a digital public library that provides physical and digital services.
