The Palace Museum has completed the compilation of its 1.8 million collections after a 10-year effort.

The collections, accounting for about 42 percent of the country's most valued cultural relics, will have their details available online for public reference by early 2013, museum staff said at a news conference on July 6.

The museum is also planning to build an entrance at the Donghua Gate, allowing visitors to get on the city wall to see the imperial architectural complex.

Shan Jixiang, director of the Palace Museum, said that this is the first time that the Palace Museum has made a thorough review of its collections, based on which the museum will publish a catalog.
