Incidentally, the first thing you need to know is that you and your fellow students must all use separate accounts. Account-sharing is forbidden. DS (talk) 20:53, 14 May 2022 (UTC)Reply

I must also inform you that copyright is complicated; as such, I cannot promise that each of the images you and your fellow students have uploaded, will be acceptable on Commons. ("But we were given permission!", you may say. That only matters if the person who gave you permission, was actually authorized to do that.) DS (talk) 21:52, 14 May 2022 (UTC)Reply
Also, you must not copy sentences from external sources. You can copy facts. I have deleted the entire section about the denazification process because you copied it from Winkelmann and Noack. This is not allowed. "We have the permission of both the main author of the article and Elsevier itself for the use of images and content", you said on my talk page, but anyone could claim to have permission to use anything. Do you have proof that Elsevier is willing to allow this content to be used under conditions that are compatible with Wikipedia's requirements? DS (talk) 22:16, 14 May 2022 (UTC)Reply
We have written again that part as you suggested, thank you very much for your help. We have added the citations that you have asked as well. Regarding the proof I have emails with Elsevier and the main author of the article about it, but as you said copying sentences is not allowed so we are changing our content to copy facts, not sentences Francesca Paielli (talk) 09:37, 15 May 2022 (UTC)Reply
I totally understand that copyright is a very complex matter but we did our best in asking to the right people and to the editor itself if we could use the images. I don't know what else we could do about it, we just hope that the images are going to be acceptable on Commomns Francesca Paielli (talk) 09:34, 15 May 2022 (UTC)Reply
Thank you very much for your reply. We used mainly my account because we where working on the page by my computer all together but my colleagues have their own accounts and they are using their account to modify and improve the page. Francesca Paielli (talk) 09:31, 15 May 2022 (UTC)Reply
