Before a magazine is hired, it will conduct a series of operations such as duplicate checking and peer review. Therefore, both magazines and university library periodicals have the account number of HowNet periodical detection system, so we can check the duplicate directly in the library or contact the editor of the magazine to check the duplicate.

Second, check the duplicate on the self-service duplicate checking website of HowNet.

When we encounter any problems, we may think of Mama Hua. If you search for copied periodicals, you will find that HowNet has many self-help websites, which are also very convenient.

Third, check the duplicate in a treasure net.

I won't say much about this. I will naturally understand what I understand.
