one of the top 500 buildings constructed in Canada during the last millennium. A Nitrate Film Preservation Facility on the Communications Research Centre campus in Shirleys Bay, on the outskirts of Ottawa, houses Canada's cellulose nitrate film collection. The collection contains 5,575 film reels dating back to 1912, including some of the first Canadian motion pictures and photographic negatives. The film material is highly sensitive and requires precise temperatures for its preservation. The state-of-the-art facility, which was officially opened on June 21, 2011, is an eco-designed building featuring an environmentally friendly roof that provides better insulation and minimizes energy expenditures. A planned key activity for 2013–14 was to rehouse analogue (non-digital) information resources in a new state-of-the-art high-density storage facility in Gatineau, where the national newspaper collection and records of Second World War veterans will be stored. The facility will feature a high bay metal shelving system with a suitable environment to better protect Canada's published heritage. In January 2019, Library and Archives Canada announced that negotiations for a new facility to be built next to the existing one in Gatineau were starting, with an opening date in 2022. LAC's online collection is accessible via its website and LAC provides ongoing information online via its blog, podcasts, the Twitter and Facebook social networking services, the Flickr image-sharing site, and the YouTube video-sharing site. RSS feeds provide links to new content on the LAC website and news about LAC services and resources. A new modernized website is being developed and is scheduled for completion in 2013, with both new and old websites accessible during the transition period.
