Now to what you can see. In October 2010 the museum opened its exhibition of presidential and vice presidential artifacts. The best-known theme is the presidential gifts, which shows presents given to presidents by friendly nations and by ordinary citizens. The collection holds more than 10,000 pieces, and displays are changed from time to time, so what you see may differ from what someone saw before you. On the second floor, the gifts are arranged by region, including Asia, Europe, Africa, and the Americas. The exhibition floor also hosts special shows drawn from the archive's collections, and the museum runs lectures on archives, artifacts, and historical themes. Guided tours are offered at set times, and groups can reserve them in advance. On the first floor you will find a digital resource reading room. Researchers can search the archive's online catalogue, read open files online, or apply to consult materials in the reading rooms. There is also a library at the Taipei site. The exhibition halls are open Monday to Friday, and on special opening days, from half past 9 a.m. to half past 4 p.m.
