 Propaganda is a subject on which we all have views and quite strong opinions but it's often a subject on which we don't always all agree. Propaganda can be iconic, it can be insidious, it can be the stuff that fits in your pocket and follows your home. We're looking at examples from the humorous to the horrific, from the subtle to the shocking. Many people now when they think about propaganda they think of it as something that's quite negative, that's something that's about lies. It's the stuff that bad people do. But really you can think of propaganda as simply trying to influence opinion or change behaviour in a way that benefits the person giving the message. Propaganda moves through different culture and media, inhabits the popular forms of its time and we'll be showing in the exhibition lots of different examples of how it does that. So here we have a monumental painting of Napoleon depicting himself as the victorious emperor in Europe. But we also look at more intimate examples, so we have for example the paper fan from the 18th century. We also have banknotes, even paper bags given to people to take things home in. There's nothing quite like seeing the actual objects and the impact that they have on you. We're familiar with some of the images but actually seeing them at scale in the way that they would have been used will be striking and challenging. In this exhibition we're really excited about the debate on propaganda, what people feel about it, what people think it is. We filmed interviews with leading practitioners, journalists and other communicators around issues of propaganda and we're really interested in your views too. You can join the debate at Twitter at BL Propaganda, tell us what you think or send us examples of propaganda. And in our final installation we'll be looking at the way that messages are choreographed through Twitter in a way that's never been seen before. So that's just the taste of some of the amazing things that you'll see in this exhibition. Book now to come and see Propaganda, Power and Persuasion at the British Library. We're open till the 17th of September.
