This book takes the form of a binder, like one of those suspension files used to keep pupils’ records in the school admin office. With recognisable ruler creases like those often seen on office stationery and a white sticker label bearing the title: American Origami. The unsettling content is the result of a six-year photographic investigation into American school shootings, neatly placed in chronological order from Columbine High School to Marjorie Stoneman Douglas High School in Parkland, Florida. Using a form of binding not, as far as we know, previously used, all the spreads in the book are stacked in landscape format and stapled on the right-hand side – including the cover. The entire body is then folded double, left to right, resulting in a very thick cahier. This allows us to leaf through this folded half, discovering one half of the book: disconcerting photos, without people, of the scenes of terrible events; portraits of those involved, cut-out school photos, interviews, Presidential speeches – each with its own distinct typography and colour or black-and-white printing. Each time, we can then lift the right-hand page, accessing the other half of the book block – a hidden section, containing photos of artefacts left behind by people at the scenes of the shootings: mementos, letters, but also social media threads from the alt-right scene. Rarely has such a highly charged topic been tackled in such an innovative way. The respect shown for the victims and the severity of the subject matter is also expressed by the incredibly painstaking way in which the technical idea has been made reality – for example, the thickness of the stack of spreads means that when the block is folded, the position of the fold moves up a little on each spread, meaning that each page has to be positioned by hand. The result is impressive; the form gives the project an additional layer and meaning. A file filled with the tragedy of a nation.
