In the 1880s and 1890s, Bardeen made a number of trips to Europe and northern Africa, and he wrote up his travel adventures for the Bulletin. He then collected the Bulletin articles and interleaved them with other memorabilia from his journeys in a number of scrapbooks. Four of these scrapbooks comprise this collection. Included in the scrapbooks are personal and business correspondence, newspaper and magazine articles, travel diary entries, cartes de visite, bills and receipts for goods purchased abroad, playbills, opera and concert programs, maps, and a number of early Kodak camera prints.
