Austria: Linz, the 2009 European Capital of Culture along with Vilnius in Lithuania, is staging an exhibition at the Linz Palace Museum about Hitler's plan to make it his capital of culture in the 1940s. Had it been built, the Fuhrer Museum would have housed 16 million stolen works of art.

Cuba: A collection of letters, manuscripts and papers that Ernest Hemingway left at his home in the hills above Havana have been digitised and microfilmed with the help of the New York-based Social Science Research Council. As part of the agreement, there are plans to deposit copies at the JF Kennedy Presidential Library in Boston.

Iraq: The World Monument Fund has launched The Future of Babylon project to conserve the ancient city and ultimately promote it as a tourist destination. The New York-based fund will work with Iraq's state board of antiquities and heritage to develop a masterplan for the site, which is 60 miles south of Baghdad. The US government has given the fund about $700,000.

Netherlands: The Dutch Museums Association has launched a project to identify works of art in Dutch museums that were looted by the Nazis. The latest round of spoliation research has government funding until 2013. It will be undertaken in partnership with the German Museums Association.

Taiwan: The directors of the National Palace Museum in Taipei and the Beijing Palace Museum plan to discuss possible joint exhibitions. This is a symbol of the recent improvement in relationships between the country's two governments. China has agreed to lend 17 artefacts to Taiwan in the autumn, but no reciprocal loan is on the table, as Taiwan fears that China still regards the island as part of its territory, and so might claim ownership of the artefacts.

US: Fisk University, in Tennessee, is seeking a reversal of a court decision that prevented it from selling a half-share of the Stieglitz collection, which was donated by the artist Georgia O'Keeffe to the Crystal Bridges Museum in Arkansas. The O'Keeffe Museum, New Mexico, maintains that it should receive the collection as the donor's "successor in interest", if the university persists with the controversial deal.

US: Neil deGrasse Tyson, director of the Hayden Planetarium, in New York, has published The Pluto Files, which were based on his experience as the US's most unpopular astronomer. Tyson received hate mail in 2000 when he downgraded Pluto, "America's favourite planet", to the status of a dwarf planet.
