The library's contents grew over the next five decades and were saved from the 1916 fire that destroyed the majority of the Centre Block; the building was only connected to the main complex by a single corridor and the library clerk at the time, Michael MacCormac, secured the library's iron doors before the fire could spread into that area. Fire eventually broke out in 1952, in the library's cupola, and caused extensive damage through smoke and water. It was then necessary to perform structural work, as well as to install a replica of the inlaid parquet floor and dismantle the wood panelling and ship it to Montreal for cleaning and partial fireproofing. The Centre, East, and West Blocks subsequently received extensive climate control and electrical upgrades, but the library was largely overlooked.
