All of the newspapers either held in the KU Libraries' collection either physically or electronically, can be found through the catalog. To locate a paper for a location when one doesn't know the name of a paper is rather easy. Simply do a keyword search with the term "Newspapers" and the location. Start with the city and if that brings up no results try the search again with the name of the nation.
Below are links to some important European papers available at KU.
