May 2019 edit

  Hello, I'm Donner60. I noticed that you made a change to an article, Nsukka, but you didn't provide a source. I’ve removed it for now, but if you’d like to include a citation to a reliable source and re-add it, please do so! If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. Donner60 (talk) 03:24, 11 May 2019 (UTC)Reply

I wrote in reply on my talk page: "Then provide a reliable, verifiable, neutral, third party source. I will place links to some helpful Wikipedia guideline pages on your talk page. Otherwise, you are not following Wikipedia guidelines. And if it is "your" page, you may have a conflict of interest and should not be editing it yourself."
See Wikipedia:Conflict of interest.
Wikipedia:No original research#Verifiability. "Main page: Wikipedia:Verifiability. Wikipedia's content is determined by previously published information rather than by the personal beliefs or experiences of its editors. Even if you're sure something is true, it must be verifiable before you can add it. The policy says that all material challenged or likely to be challenged, and all quotations, needs a reliable source; what counts as a reliable source is described at Wikipedia:Verifiability#Reliable sources."
Wikipedia:Verifiability#Reliable sources. "Base articles on reliable, third-party, published sources with a reputation for fact-checking and accuracy. Source material must have been published, the definition of which for our purposes is "made available to the public in some form". Unpublished materials are not considered reliable."
Wikipedia:Verifiability#Responsibility for providing citations. "All content must be verifiable. The burden to demonstrate verifiability lies with the editor who adds or restores material, and is satisfied by providing an inline citation to a reliable source that directly supports the contribution."
Wikipedia:Verifiability, not truth#Editors are not truth finders. Essay. "Wikipedia editors are not indifferent to truth, but as a collaborative project, its editors are not making judgments as to what is true and what is false, but what can be verified in a reliable source and otherwise belongs in Wikipedia."
Wikipedia:Verifiability. "In Wikipedia, verifiability means that other people using the encyclopedia can check that the information comes from a reliable source. Wikipedia does not publish original research. Its content is determined by previously published information rather than the beliefs or experiences of its editors. Even if you're sure something is true, it must be verifiable before you can add it. When reliable sources disagree, maintain a neutral point of view and present what the various sources say, giving each side its due weight."
