Queen Elizabeth College and Chelsea College of Science and Technology in 1985, and the Institute of Psychiatry in 1997. In 1998 the United Medical and Dental Schools of Guy's and St Thomas' Hospitals merged with King's to form the GKT School of Medical Education. Also in 1998 Florence Nightingale's original training school for nurses merged with the King's Department of Nursing Studies as the Florence Nightingale School of Nursing and Midwifery. The same year King's acquired the former Public Record Office building on Chancery Lane and converted it at a cost of £35 million into the Maughan Library, which opened in 2002.
