The Library completed its immediate salvage operation of collections located in the fire affected areas [yesterday] and is in the process of relocating over 70 staff to other parts of the building.
We’re keen to stress that it’s business as usual at the Library, for readers, users and visitors. On Friday we took the precautionary measure of cancelling a few of this week’s planned events, but, apart from that, we’re confident that we can provide a full and normal service to all our users.

David Cameron and David Jones fired several shots at the Welsh Government during the Conservative conference in Swansea.
The Prime Minster compared Carwyn Jones' administration to the "Muppet Show" in what many saw as a speech designed to galvanise the party's grassroot as the party look towards the 2015 general election.
Welsh Secretary David Jones went further, criticising Business Minister Edwina Hart's handling of Enterprise Zones as "Soviet style developments' and urging the Welsh Government to follow the UK Government's model.
He criticised planning policy and described plans to install sprinklers in new houses as "bizarre."
The Clwyd West MP said "people don't care where policy is developed...we have to cooperate if we are to succeed."
When the Tories took office "the respect agenda" was the watch phrase. No mention of that today as the party seemed to be stepping up its efforts for a Conservative Government in 2015.

Arwel Jones from the National Library of Wales told ITV News that he is hoping that the damage will be limited - "the most valuable stuff is housed in purpose-built cells at the very bottom of the library, and this fire is at the very top."
He admitted to concern that the damage from water pumped onto the building by firefighters would be as bad as the fire damage.
