I'm collecting data on important business and economic news dates in the late 19th to early 20th century. The only list I found is this: https://www.encyclopedia.com/history/news-wires-white-papers-and-books/1878-1899-business-and-economy-chronology. I'm trying to identify dates in which there were important news for the U.S. stock market.
Does anybody know of any other sources? Perhaps another encyclopedia, a news article, or an academic paper?
