ZSR's Special Collection and Archives may contain useful materials on your topic. There are a variety of ways to search these materials, depending on their format. The SCA website contains more information about hours and research help. 

1. Search SCA materials (including books) in the library catalog. These include rare books from going back to the 17th and 18th century, such as travel narratives and papers from various figures in British history. 

Example:

• A relation of a journey to Constantinople : Giving an account of divers occurrences; how far the king of Sweden's commission was executed there; as also of the state of the Turkish monarchy at that time, being a report made to the most potent prince, Charles Gustavus, king of the Swedes, Goths, and Vandals. (1745)

2. Search SCA finding aids to locate materials in collections that are not digitized. (Visit the Special Collections and Archives room in ZSR 625 for help using finding aids!)
