The National Cyclopaedia of American Biography is a multi-volume collection of biographical articles and portraits of Americans, published since the 1890s.
[1] The primary method of data collection was by sending questionnaires to subjects or their relatives.
It is more comprehensive than the Dictionary of American Biography and the American National Biography, but less scholarly because it does not cite the original sources used for the information.
