Public libraries in Cardiff are owned and operated by Cardiff Council. There are 20 public libraries in the capital of Wales, the largest of which is Cardiff Central Library. A mobile library service is also provided. In 2009/10, there were nearly 80,000 Cardiff residents, around 25% of the city's population, who borrowed an item from a municipal library. Cathays and Canton Libraries are both Carnegie Libraries, built with money donated by Scottish businessman and philanthropist Andrew Carnegie.
