Against this concentrated core, the four hundred remaining authors provide the bibliography’s granular worldliness. They introduce cases, scales, traditions, geographies, methods, sensitivities and historical layers that keep Socioplastics from becoming excessively self-enclosed. One might say that the twenty produce coherence, while the four hundred produce respiration: the first stabilise the architecture; the second ventilate it. The most important developmental task is therefore not simple enlargement, but the cultivation of an intermediate zone of bridge authors capable of mediating between the founding axis and the expansive periphery. Latour, Haraway, Hayles, Star, Simondon, Stengers, Mattern, Bowker and Easterling could become especially productive here, not necessarily through greater citation volume, but through more strategic placement across node families. A mature field does not erase its origin; it makes that origin inhabitable by others. Socioplastics’ bibliography thus becomes an infrastructure of orientation: concentrated enough to remain legible, broad enough to remain porous, and plastic enough to let the periphery participate in the future shape of the field.
