Hans Ulrich Obrist, "In conversation with Julian Assange," Part I, e-flux journal #25 (May, 2011), and his inkling of the bloc as a squarely defined, eternally immutable unit of information, and its preeminence of being the successor of the book :

• a large quantity or allocation of things regarded as a unit.

• a large piece of text processed as a unit .

• an obstacle to the normal progress or functioning or flow of something.

• to design or plan the movement of agents in a given theatre or space.
