The very extensive library collection of Gerard Nicholas Heerkens (1726–1801), the cosmopolitan Dutch physician and Latin poet, was sold at auction between 23 and 28 September and between 14 and 21 October 1805 at the University of Groningen. The auction was organized by the antiquarian and book dealer Jan Hendrik Bolt (active 1779–1845), who prepared the catalogue.
