Abstract: The construction of library resource sharing is the pursuit of library for a long period of time. The rapid development of network technology not only reduces the cost of resource sharing, but also improves the efficiency, providing a great convenience to the readers. Based on the development and necessity of library resource sharing under network environment, this paper analyzed the significance of resource sharing, and studied the contents of library resource sharing, including document entity sharing, bibliographic resource sharing and service sharing. And at the same time, aiming at the existing problems in the construction process of library resource sharing, like the intellectual property protection, the shortage of funds, and the lack of unified planning and standards, it put forward the strategies from strengthening the protection of intellectual property rights, introducing market mechanism and improving resource sharing standards and norms, so as to make full use of the network approach to realize the resource sharing of the library.
