Series 1. On April 24, 1858 for instance, Frank Leslie's Illustrated Weekly in New York published an extensive article about one William Francis, a New York physician and inventor, who had developed a writing machine. The article actually says he sold several of the machines for 100 dollars a piece. None of his machines have survived.
An interesting detail in the article is that Francis also invented a mechanical cane that could hold small coins. The contraption was intended to help one pay his bus fare without falling over. It was difficult to stay on your feet in horse drawn public transport.

Series 2. In september 1894, the Journal of the Society of Arts in London, devoted two issues to present a lecture on the history and develpment of the typewriter.

Series 3. The Illustrated London News featured a report on the London world exhibition on Sep 1, 1891. In a full page illustration it showed two ladies demonstrating the North typewriter to an international audience. China and the Ottoman empire were clearly represented in the crowd.

Series 4. The most famous typewriter publication is that of August 10 1872 about the Sholes Type Writer. Note the fourth picture with a letter to the editor by Carlos Glidden, complaining about the fact that his name wasn't mentioned in the article.
