A journal European Chemical Bulletin was added in the scopus source list in the month till June 2023. In the month July 2023 it is out from scopus list. But it will not be considered in the scopus from December 2022, Volume 11, Issue 12, Pages 22-38. How much it is justified the validity of scopus. And what about those papers that were published between January to June 2023 (these published papers bydefault will out from the scopus). Due to this glitch and wrong policy of the scopus, one thesis has not been accepted. Why the scopus has not taking seriously to update the data every month or every day. And if any journal excluding from the souce then it should be excluded from the current month, not from previous 6-7 months. I think scopus papers should not be in the creteria of thesis submission. What do you think about this a big issue.
