Wikipedia:Copyright problems/2018 январь 26

I just added the url to the paragraph in that article "Charles E. Spahr" where citation was needed. It is like this - But I am not sure about copyright violation policy. Help me please with my further actions if any. What am I supposed to do now. May be it's rather a copy and paste problem instead of copyright because the content of the article is completely the same with the source. And copyright on the contrary is in full correspondence with Wiki copyright policy.
