The title of the paper has been published and the journal has been received, but it is not included in the electronic collection, so the verification of the paper cannot be verified. What should I do?
Look at your rules. Can you submit the scanned version of the journal cover and the scanned version of the article content for verification, or submit the paper articles and documents for verification? Let the editorial department send the electronic version of the notice of joining the club and the DOI stamped with the official seal, and then print it in color. If time permits, send the paper version by express mail.
