A tag has been placed on Fibrations of graphs requesting that it be speedily deleted from Wikipedia. This has been done under section G12 of the criteria for speedy deletion, because the page appears to be an unambiguous copyright infringement. For legal reasons, we cannot accept copyrighted text or images taken from other web sites or printed material, and as a consequence, your addition will most likely be deleted. You may use external websites or other printed material as a source of information, but not as a source of sentences. This part is crucial: say it in your own words. Wikipedia takes copyright violations very seriously and persistent violators will be blocked from editing.

If the external website or image belongs to you, and you want to allow Wikipedia to use the text or image — which means allowing other people to use it for any reason — then you must verify that externally by one of the processes explained at Wikipedia:Donating copyrighted materials. The same holds if you are not the owner but have their permission. If you are not the owner and do not have permission, see Wikipedia:Requesting copyright permission for how you may obtain it. You might want to look at Wikipedia's copyright policy for more details, or ask a question here.

If you think this page should not be deleted for this reason, you may contest the nomination by visiting the page and clicking the button labelled "Contest this speedy deletion". This will give you the opportunity to explain why you believe the page should not be deleted. However, be aware that once a page is tagged for speedy deletion, it may be deleted without delay. Please do not remove the speedy deletion tag from the page yourself, but do not hesitate to add information in line with Wikipedia's policies and guidelines.

Hi Vigna, I wanted to add a bit to the generic message above. Based on your username, I'm assuming that you are the Sebastiano Vigna who holds the the copyright to the content at https://vigna.di.unimi.it/fibrations/. Wikipedia can only accpet content that is published under a compatible license, as described at Wikipedia:Copyrights. Because the info from your webpage is copyrighted, and not published under a CC BY-SA license or similar, we cannot publish it verbatim. If you would be interested in publishing that material under a free license so that it can be transferred to Wikipedia, let me know and I'll try to direct you to some resources to help with that.

I already sent an email to permission-en. Is there any thing else I should do? Vigna (talk) 21:57, 2 March 2026 (UTC)

I can add a link to CC BY-SA or similar license to the original page, if that's simpler for you. Vigna (talk) 21:58, 2 March 2026 (UTC)

I linked a Creative Commons C0 (public domain) logo. Vigna (talk) 22:15, 2 March 2026 (UTC)

Pinging Justlettersandnumbers for visibility. Is this something you're able to assist with? Zeibgeist (talk) 23:54, 2 March 2026 (UTC)

Vigna, the page in question is still marked "©2026 Sebastiano Vigna. All rights reserved". Perhaps I'm wrong, but I don't see how that is compatible with the CC0 statement in the page. If my understanding is correct, copyright is not retained under that licence, but is retained under a CC BY-SA 4.0 licence (which might for that reason be a preferable choice). If you could kindly sort out that apparent conflict, I'll be pleased to remove the blanking template from the article page. Regards, Justlettersandnumbers (talk) 09:15, 3 March 2026 (UTC)

I'm sorry, you're right—I forgot about the blurb at the bottom. I replaced the blurb with "The content of this website is licensed under a Creative Commons Attribution-ShareAlike 4.0 International License", linked to CC BY-SA. Vigna (talk) 09:49, 3 March 2026 (UTC)

Hello Vigna! We welcome and appreciate your contributions, such as Fibrations of graphs, but we regretfully cannot accept copyrighted material from other websites or printed works. This article appears to contain work copied from https://vigna.di.unimi.it/fibrations/, and therefore to constitute a violation of Wikipedia's copyright policies. The copyrighted text has been or will soon be deleted. While we appreciate your contributions, copying content from other websites is unlawful and against Wikipedia's copyright policy. Wikipedia takes copyright violations very seriously, and persistent violators are likely to lose their editing privileges.

If you believe that the article is not a copyright violation, or if you have permission from the copyright holder to release the content freely under license allowed by Wikipedia, then you should do one of the following:

• Have the author release the text under the Creative Commons Attribution-ShareAlike 4.0 License (CC BY-SA 4.0) by leaving a message explaining the details at Talk:Fibrations of graphs and send an email with confirmation of permission to "permissions-enwikimedia.org". Make sure they quote the exact page name, Fibrations of graphs, in their email. See Wikipedia:Requesting copyright permission for instructions.
• If you hold the copyright to the work: send an e-mail from an address associated with the original publication to permissions-enwikimedia.org or a postal message to the Wikimedia Foundation permitting re-use under the Creative Commons Attribution-ShareAlike 4.0 License and GNU Free Documentation License, and note that you have done so on Talk:Fibrations of graphs. See Wikipedia:Donating copyrighted materials for instructions.
• If a note on the original website states that re-use is permitted "under the Creative Commons Attribution-ShareAlike License (CC BY-SA), version 4.0", or that the work is released into the public domain, or if you have strong reason to believe it is, leave a note at Talk:Fibrations of graphs with a link to where we can find that note or your explanation of why you believe the content is free for reuse.

It may also be necessary for the text to be modified to have an encyclopedic tone and to follow Wikipedia article layout. For more information on Wikipedia's policies, see Wikipedia's policies and guidelines.

See Wikipedia:Declaration of consent for all enquiries for a template of the permissions letter the copyright holder is expected to send.

Otherwise, you may rewrite this article from scratch. If you would like to begin working on a new version of the article you may do so at this temporary page. Leave a note at Talk:Fibrations of graphs saying you have done so and an administrator will move the new article into place once the issue is resolved.

Thank you, and please feel welcome to continue contributing to Wikipedia. Happy editing! Justlettersandnumbers (talk) 21:22, 2 March 2026 (UTC)

The link to the temp page shows an empty editor—I really, really hope you did not lose my work. Vigna (talk) 22:00, 2 March 2026 (UTC)

Ah no ok, that's for rewriting from scratch (something I definitely do not intend to do). Vigna (talk) 22:02, 2 March 2026 (UTC)
