Crossing Borders, Bridging Generations (CBBG) was an oral history project and public programming series sponsored by Brooklyn Historical Society from 2011 to 2014. CBBG was designed to examine the history and experiences of mixed-heritage people and families in Brooklyn. The project also explored the broader themes of cultural hybridity, race, ethnicity, and identity formation in the United States. CBBG was created by Sady Sullivan, Director of Oral History at Brooklyn Historical Society from 2006-2014, and the project was funded with assistance from public and private grants. CBBG expanded upon Brooklyn Historical Society’s oral history collection, which was founded in 1973 and contains interviews with over 1200 narrators.
