I'm not sure if it's new, or new to me, but I've just discovered Te Ara's 'Creative and Intellectual Life' section.*
Sections include Roger Blackley on the history of art galleries and collecting, Peter Ireland on photography and Rebecca Rice and Mark Williams on criticism (art and literary). Other sections include anthropology, libraries, theatre design and more.
*The section title is happy-making in itself - unapologetic and standing tall in a time whne where I'm looking for art stories on a newspaper site I generally have to make a call between 'lifestyle' and 'entertainment'.
