The work of Ferdo Šišić is characterized by a systematic, objective and informed approach. His opus, however, is the high point of "genetic history" or the archivist's approach, which patiently weaves the tapestry of the chosen period without engaging in speculations that are sometimes necessary to fill the gaps left open by archive materials. Also, the Croatian historiography came to be dominated by the multidisciplinary approach combining demographics, culturology, history of economy and art only in the second half of the 20th century, putting Šišić in the position of a classic who laid inestimable foundations but cannot be the role model for contemporary historical science.
