It was a common practice for 19th-century newspapers to republish poems, fiction excerpts, and even lists of facts that were originally published elsewhere. Editors would subscribe to many newspapers and would cut out things they thought were interesting, relevant, or fit a space on the page that they needed to fill and then republish them in their own papers, Cordell explained.
“Many 19th-century newspapers are comprised primarily of content from other newspapers,” he said. “They were more aggregators than producers of original content. And often they were created by very small staffs, and scholars such as Ellen Gruber Garvey have shown that this aggregation is what allowed newspapers to spread as rapidly as they did in the 19th century, because you didn’t have to produce the whole thing.”
