In this study, the authors investigated the applications of virtual reality technology（VRT） in university libraries in China and abroad.  Specifically, their investigations were done from 4 aspects, namely, virtual tour, 3-dimensional resource construction, virtual references and information retrieval.  Then they compared the applications in China and abroad, finding that both Chinese and foreign university libraries have started to apply VRT on the aforesaid four fields but almost no library provide deep applications.  Moreover, foreign universities and Chinese universities have different styles in using VR. Specifically, foreign university libraries prefer applying VRT on “second life”, which is a virtual platform, while Chinese university libraries prefer using it on their homepage.  Chinese university libraries prefer applying VRT in virtual tour while foreign university libraries prefer using it in virtual browse.  Chinese university libraries prefer using VRT on freshman education while foreign university libraries provide their services to everyone.
