Since the turn of the millennium, the photobook has rapidly become the central form of expression in photography. Thanks to digital technology, more photobooks have likely been published in the past ten years than in the previous 170. The mission of the museum will be to promote the photobook as an independent artistic medium. The museum is intended to be a vibrant public space that educates a broad audience about the form, content and function of photobooks. In order to show what the future museum can achieve in this respect, a temporary pilot-version was presented as an exhibition on the grounds of the Carlswerk industrial site in Cologne-Mülheim, from August to October 2014.
