The Ernest & Marion Davis Library opened in 1961 as the main medical library for Auckland Hospital. Sir Ernest Davis had donated the building to the medical profession in memory of his wife Marion, plus an endowment fund to support the running of the library.
In 1980 the bulk of the books were transferred to the new Philson Library in the School of Medicine. At that time the building was modified to provide postgraduate facilities which include a lecture hall, dining room and meeting rooms. The remaining space was reorganised to incorporate a collection of historical medical books and the acquisition of historical medical artefacts. This includes two superb collections of ancient apothecary Jars, numerous microscopes, instruments, assorted artworks and ephemera.
In 2014 the building was earthquake strengthened & underwent extensive renovations providing the opportunity to showcase many of the interesting objects held in storage.
