Hackney's new library is now open in the heart of Dalston, just to the north of De Beauvoir.
At 2,964 square metres over three floors, the Dalston CLR James Library is one of the largest libraries in the UK, more than twice the size of the previous facility.
As well as 17,000 books for adults, 9,500 for youngsters and 200 talking books there are 1,600 CDs/DVDs.
The library includes 20 dedicated study spaces and 2 meeting rooms along with free use of 57 computes and free wi-fi.
There will also be a cafe on the site (opening later in the year) managed by a local business.
Hackney Archives, previously located in De Beauvoir ward, have a new home in the building. The collection includes historic photographs and original council records. The full archive will open soon after the library.
The library, as with the previous building, is named after CLR James, a Trinidadian historian, journalist and social theorist.
