The Law on Public Libraries in our country clearly defines thefunction of Public Libraries. Public libraries can provide digital resources tothe public. Public access to digital resources for learning has been normalizedin the network environment. Due to the limitation of copyright rules, thefunction of preserving and inheriting digital resources in public libraries hasbeen weakened, and public access to digital documents has been hindered.The convenience of obtaining digital resources and the daily research of digitalresources have made people try to apply the copyright rules of current textresources to the digital resources. However, no feasible solution has beenformed. It is not appropriate to copy the existing rules for copyright rules ofpublic libraries to acquire digital resources, but should pay attention to thebalance of interests among all the subjects.
