The scrapbooks of Joannes Gennadius are one of the most important collections of the Gennadius library, as they contain invaluable information for the history of modern Greece but also for life in London during the turn of the 20th century. In his scrapbooks, Joannes Gennadius collected photographs and other ephemera (clippings from newspapers and books, engravings, printed matter, broadsides, invitations and many other materials). The 116 volumes of the scrapbooks focus on diverse topics: history, topography, archaeology, ethnology (costume books), architecture, art history, history of the book, journalism as well as the Gennadius family. Each volume consists on the average of 60-70 pages of large size. Part of the scrapbooks have been digitized and this is what is presented here.
