The first study of the Carnegie libraries built in Wales in the Edwardian Age.As 'the richest man in the world', the book illustrates Carnegie's commitment to the provision of free and public libraries for all, regardless of age and gender.The buildings were - and in many cases still are at the heart of towns and industrial communities across Wales (as they were elsewhere in the USA and the British Empire). The libraries shed light on the social, political, cultural and architectural history of Edwardian Wales.
