Shera's social epistemology recast as psychological bibliology

Shera, the library scientist, is often credited with introducing the term and concept of social epistemology; but his idea is most profitably viewed not as a contribution to epistemology or even to the sociology of knowledge, but rather as the forerunner of a document-focused strain of socio-cognitive psychology influential in the information sciences from the 1970s onwards. In turn, the work of Shera and his colleague Egan is itself reminiscent of the psychological bibliology defined by the documentalists Otlet and Rubakin in the early 20th century.
