The five Divisions of the Academy each draw together scholars representing a different, broad field of science – mainly national and foreign members of the Academy.
The Divisions each oversee a set of research units situated throughout the country and coordinate their efforts. They represent also the Polish research community in their respective fields and promote their achievements, as well as facilitate cooperation with centers in Poland and abroad.
They likewise supervise certain auxiliary scientific units, such as archives, research stations and centers. Each Division also embraces a set of scientific committees, task-force committees, and national committees.
