The Hyman Kreitman Research Centre opens on Wednesday, fulfilling a longstanding aim of the Tate to increase public access to its substantial research resources. Funded by a £2.2 million donation by the Kreitman foundation, the new centre offers an increased number of places for users and for the first time brings together the Tate's existing library and archive collections (including Picasso on the beach at Juan-les Pins, right).
