Please read the explanation of limited access to resources on Guo Tu website carefully. If you are a reader of Guo Tu and have a library card, please log in with your account and try again. I don't think it's expensive or troublesome to get a library card to Guo Tu. Now you can do it with your ID card, which costs 5 yuan a year. Actually, it's not dark. You can also use library resources on the spot, which is more convenient and reliable (I don't know why you are so superstitious about online reading). The openness of digital resources in Guo Tu is not low, and many foreign book resources need more rights to use, such as OED online, a famous Oxford English dictionary. Unregistered users can't even find a word.

Q: After I log in successfully, why is my access to some resource systems restricted?

A: This system provides readers with a simple way to access multiple resource systems. Different resource systems control readers' access rights, which can be divided into the following situations:

(A) the use of limited resources

(1) The use of Chinese books, doctoral dissertations and audio-visual resources in the library is restricted due to copyright issues. Due to copyright restrictions, services are currently provided to readers on the Internet, so readers can only read or appreciate part of each volume/article.

(2) Due to different types of users, the use of readers is restricted.

(b) Use unrestricted resources

No matter registered users or anonymous users, the use of resources such as documents of the Republic of China, digital local chronicles, documents of Oracle Bone Inscriptions and Xixia is not restricted.
