U.K. indie trade body AIM is linking up with its U.S. counterpart A2IM to provide reciprocal access to a range of online resources on each market.

Both groups are already members of the Worldwide Independent Network (WIN), but this will begin a new process of sharing resources including 'how to' guides, contact directories, legal and business affairs journals and event journals.

"Knowledge is power in business, and having access to market information and relevant industry contacts is vital," said AIM chairman and CEO Alison Wenham. "This collaboration between AIM and A2IM will allow members of both to increase their knowledge, contacts and understanding of the market across the pond."

Both groups hope to develop similar partnerships with other members of WIN, enabling indies worldwide to share market information and resources.

Meanwhile, it's been confirmed that London's Institute of Contemporary Arts will host five nights of showcases from July 6 to July 10 as part of the 2009 Independents Day celebrations.

Following the launch of Independents Day in 2008 by WIN and the U.K.'s Association of Independent Music (AIM), the event returns to highlight the achievements of independent music around the world.

The 2009 event has been organized in conjunction with Live Nation. Independent retailer Rough Trade East will curate July 7, alongside AIM member labels Bella Union (July 6), Beggars Group (July 8), Fat Cat and One Little Indian (July 9), and Ninja Tune (June 10).

Huw Stephens of national top 40 station BBC Radio 1 will introduce the first two nights.

"Independents Day is already a firm fixture in the calendar after just one year, and even more ambitious plans for next year are already underway," said Wenham.
