Joshua "Josh" M. Greenberg (born 1976) is an American academic working in sociology of scientific knowledge.

[4] Greenberg's doctorate from Cornell in 2004 was conferred on the basis of a thesis, From Betamax to Blockbuster: Mediation in the Consumption Junction (OCLC 58539393).

In this work, Greenberg argued that the evolution was less a physical transformation than a change in perception, but one that relied on the very tangible construction of a network of social institutions.

Greenberg served NYPL in a newly created position as the Director of Digital Strategy and Scholarship,[2] which means that he was actively involved in determining what the job would become.

In 2007, NYPL established an innovative working relationship with Kaltura, an open-source platform for media which can then be embedded and played elsewhere on the Internet.

[11] The team headed by Greenberg is refining digital-scholarship components for a major Library exhibitions, including the one on Yaddo.

[16] Greenberg's strategy led to NYPL investment in the development of Flickr Commons, including the challenges and costs of building and maintaining a "virtual reading room" and lessons learned the hard way.
