UBC's Main Library underwent major renovations beginning in 2002. In phase one, the north wing was demolished and rebuilt. It now houses the bookstacks of the facility. Once the renovated north wing opened, the old south wing and "heritage core" of the Main Library was closed, with the south wing being demolished and the heritage core stripped to the original frame and exterior from 1925. The South Wing was officially opened to the public on February 25, 2008, with the heritage core opening in late March 2008. The building is now known as the Irving K. Barber Learning Centre, named in honour of donor Irving K. Barber.
