Biesboer's introductory essay provides an in-depth survey of the history of collecting in Haarlem during the seventeenth and early-eighteenth centuries. The inventories of citizens, patricians, merchants, artists, and silversmiths are included, along with the inventories of the Convent of Saint Jan, the Prinsenhof, Saint Elisabeth's Hospital, the Old Men's Almshouse, the Orphanage, and other almshouses. Together they present a comprehensive look at commissioned paintings for public buildings and institutions by artists such as Cornelis Cornelisz van Haarlem, Frans Hals, Johannes Verspronck, and Cornelis Holsteijn. In addition to paintings, Biesboer catalogues a small number of drawings, porcelain, lace, sculpture, and jewelry.
