Is this page plagiarism, or has it been plagiarized? edit

I found a page with identical wording for much of the opening paragraphs here: https://poulwebb.blogspot.com/2021/09/pulp-fiction-1910s-1920s-part-1.html

Did the person who made the opening section here plagiarize from that blog, did the blog plagiarize from Wikipedia, or is something less nefarious going on (e.g. an author releasing their own words to Wikipedia yet also using them for their own blog)? Kilyle (talk) 09:43, 29 August 2023 (UTC)Reply

That blog took their text from Wikipedia. You can tell by looking at a version of this page from before the date on the blog. Mike Christie (talk - contribs - library) 11:09, 29 August 2023 (UTC)Reply
