Professor Henry Warwick, in collaboration with Telekommunisten, presented workshops at the Transmediale Festival in Berlin that pertain to his focused work and research on Personal Portable Library (PPL) systems. Datafield2 is a network attached storage unit that builds on the theme of common ordinary household information appliances. It can be moved and re-located and acts as a repository for data - anyone can buy one, fill it with data and leave it in a public place. Datafield3 is a set of USB sticks that provide a method of using text messages to find hidden devices. The workshops aim was to discuss the features and principles of PPLs and how they can be constructed.
