In addition to the new sources listed in the Getting Started tab, Penn Libraries subscribes to online access to many newspapers from around the world. Keep in mind that your project will use primarily academic sources. However, news sources might be used to complement the more scholarly sources you find so as to emphasize the real-time prevalence or significance of the topic
Find out about additional options by talking with your librarian and/or reviewing the Penn Libraries' guide to American Newspapers
