Xi' an library is good. Although Shaanxi Library is more famous and has more books than xi 'an Library, there are not so many books available for provincial libraries to borrow. At present, Xi 'an Library and provincial maps are both unmanned libraries. If you want to find books such as novels and literature, I suggest Xi 'an Library and technical books, and then Shaanxi Library. In fact, if you are a reading enthusiast, I think both libraries will definitely go there often.
