Dana Library and Research Centre Announced by the Science Museum

The Science Museum in London has officially announced the new Dana Library and Research Centre, opening in late 2015. As envisioned by the Science Museum, the new Centre will provide a “world class environment” for academic research and it will be open to the public as well. Renovation is now underway at the former Dana Centre, which opened in 2003 and provided public events about the latest in science research.

  For academic research, the Centre will focus on bringing together the Museums’ library and archive collections, as well as artifacts, through its Research and Public History Department. The facility will be open to the public and include special events aimed at reaching broad audiences.

  Edward Rover, Chairman and President of the Dana Foundation said, “We are delighted that the Library and Research Centre preserves the Dana name. We have a longstanding relationship with the Science Museum and the focus of the new facility is in keeping with Dana’s mission and commitment  to the importance of scientific inquiry and public education. ”
