Auckland City Libraries was a network of 17 public libraries and a mobile library operated by Auckland City Council. In November 2010, Auckland's local councils merged to create the Auckland Council, which meant that the Auckland City Libraries network was merged with six other Auckland public library systems to form Auckland Libraries. Auckland Libraries is currently the largest public library network in the Southern Hemisphere with 55 branches from Wellsford to Waiuku.
The building that currently houses the Central City library was opened in 1971. Despite the merging of the libraries, Auckland City Libraries still exists in the form of a separate digital entity: it has a separate website and digital library with a variety of resources including eBooks, online encyclopaedias, and digitised newspapers and journals.
