Bibliography of History of the Czech Lands (BHCL) is a continuous programme of generation, processing and evaluation of the complex bibliography database of bohemicist literature, linking up to the project of the subject (historical) bibliography, which has been continually developing in Bohemia since 1905. BHCL develops these activities using modern methodology and belongs to the key information resources for historical science and related fields (e.g. archaeology, ethnology, legal science, literary science, monument preservation, historical geography and cartography, historical onomastics and toponomastics, historical demography, etc.). It consists in the existing infrastructure carried out within the scope of the research objective of the Institute of History of the Academy of Sciences of the Czech Republic.
