• A new website has been launched to showcase the UK’s vast national collection of oil paintings. While the website, which is a partnership between the BBC, the Public Catalogue Foundation, and participating collections and museums, currently hosts around 60,000 works, it is envisaged that by the end of 2012 it will carry digitised images of all 200,000 oil paintings in the UK (in an indicator of how many there are, the National Gallery currently has around 2,300 oil paintings, about one hundredth of all those in the nation). The works on the site will eventually include almost 40,000 by British artists. The 850 galleries and organisations participating so far include 11 in London – among them the National Gallery, the Tate Gallery, the Victoria and Albert Museum, the Bank of England, the Imperial War Museum and Dr Johnson’s House.

• Arctic explorer John Rae has had a Blue Plaque unveiled in his honor at his former home in Holland Park. Although his feats were relatively unsung in his lifetime, the explorer’s expeditions in the Canadian Arctic saw him travel 13,000 miles by boat and foot and survey more than 1,700 miles of coastline. He is also credited with having “signposted” the only north-west passage around America that is navigable without icebreakers. Rae, who died in 1893, lived at the property at 4 Lower Addison Gardens in Holland Park for the last 24 years of his life.

• Transport For London is calling on Londoners to share experiences of “kindness” that they have witnessed or participated in while travelling on the Underground. Artist Michael Landy has created a series of posters which are calling on people to submit their stories. Some of the stories will then be shown at Central Line stations (the first four posters go up on 23rd July at stations including Hollard Park, Holborn and Liverpool Street).

More to come on that.

• On Now: Toulouse-Lautrec and Jane Avril Beyond the Moulin Rouge. The Courtauld Gallery, based at Somerset House, is running an exhibition celebrating the “remarkable creative partnership” between Jane Avril, a star of the Moulin Rouge in Paris during the 1890s, and artist Henri de Toulouse-Lautrec. Lautrec created a series of posters featuring Avril which ensured she became a symbol of Lautrec’s world of “dancers, cabaret singers, musicians and prostitutes”. Runs until 18th September.
