John Rylands Library has been extended four times, the first time to designs by Champneys in 1920 after the project was delayed by World War I. The Lady Wolfson Building opened in 1962 on the west side and a third extension, south of the first was built in 1969. In January 2003, an appeal to renovate the building was launched.
