Members of the International Centre for Diffraction Data met during the week of 14 March 2011 for the Annual Spring Meetings. Members from 11 countries gathered, along with staff and guests, at ICDD headquarters, Newtown Square, PA, to learn about ICDD's educational events, database, and product developments over the past year, and to reconnect with one another. Throughout the week, various committees, subcommittees, and task groups met for special-interest discussions. For the first time ever, the ICDD offered a live, online broadcast of the Technical Committee Meeting and the Annual Meeting, which took place on Thursday, 17 March. The talks from these meetings will be available online for rebroadcasting at a future date. Many were in attendance for the plenary session, which was held on Tuesday, 15 March.
