Past conferences have typically been held on Friday through Sunday. However, the show's organizers have announced a change for the 2014 show: it will be held on Thursday, Friday, and Saturday, 20 to 22 February, 2014.
The format of the 2014 will remain similar to past events: more than 150 free workshops, free services which can identify and date military memorabilia and old photographs, and the chance to spend time with a genealogy expert plus Eric Knowles on standby to look at your family heirlooms. All in all, this should again be a great event.
The venue will remain the same: at the Olympia Centre in West Kensington, part of greater London. The Olympia Centre itself has quite a history, having opened in 1886. It is a huge venue and is easily reachable by rail. The nearest railway station is Kensington (Olympia) station which serves as both a London Overground station and, on weekends, a District Line station on the London Underground.
