weighing scales, laboratory equipment, pharmacy furniture, forms, documents on pharmaceutical and medical topics, packaging for medicines, postcards and medical tools. One of the most valuable exhibit is the original galenic laboratory from the late 19th century, preserved in situ and unique in Poland. It originally produced drugs from plant, animal and mineral raw materials. The 1875 pharmacy furniture comes from the pharmacy Pod Łabędziem in Toruń. It was brought to Bydgoszcz at the beginning of the 21st century so as to replace the original furnishings, which was beyond repair after being nationalized in 1951. Library Location: 4 Mennica Street Books and magazine collections date back to the 1880s. The most valuable item of the book collection from that period is the Jahrbuch der Historischen Gesellschaft für den Netzedistrikt zu Bromberg, from 1891–1895 (Yearbook of the Historical Society for the Netze District in Bromberg). The inventory of the library collections began in January 1925. In the 1960s, the collection was organized with an alphabetical and subject-systematic catalog and a catalog of periodicals. Since 2009, a computer catalog is also available.
