Art critic Jerry Saltz is regarded as a pioneer of online art criticism by the mainstream press, yet the Internet has been used as a platform for art discussion for over 30 years. There have been studies of independent print-based arts publishing, online art production and electronic literature, but there have been no histories of online art criticism. In this article, the author provides an account of the first wave of online art criticism (1980–1995) to document this history and prepare the way for thorough evaluations of the changing form of art criticism after the Internet.

The Sublimity of Document: Cinema as Diorama (Avant-Doc 2) is an international collection of in-depth, substantive interviews with moving-image artists working “avant-doc,” that is, making films that explore the territory between documentary and experimental cinema. The Sublimity of Document follows on MacDonald’s earlier Avant-Doc: Intersections of Documentary and Avant-Garde Cinema (Oxford, 2015), though the focus here is on filmmakers who are committed to document itself, willing to go anywhere on the planet (or within film archives or on the internet) to document what they believe we need to see—regardless of whatever political implications the film experiences they create may have for us. The book uses the early history of the museum habitat diorama of animal life, specifically the Akeley Hall of African Mammals at the American Museum of Natural History, as a way of rethinking both early and modern cinema of document—and especially those recent filmmakers and films devoted to providing a panorama of places and events that viewers might never have opportunities to experience in person. The twenty-seven interviews in The Sublimity of Document are organized panoramically within the volume.

By 1940, a half dozen or so commercial or home-built transmission electron microscopes were in use for studies of the ultrastructure of matter. These operated at 30-60 kV and most pioneering microscopists were preoccupied with their search for electron transparent substrates to support dispersions of particulates or bacteria for TEM examination and did not contemplate studies of bulk materials. Metallurgist H. Mahl and other physical scientists, accustomed to examining etched, deformed or machined specimens by reflected light in the optical microscope, were also highly motivated to capitalize on the superior resolution of the electron microscope. Mahl originated several methods of preparing thin oxide or lacquer impressions of surfaces that were transparent in his 50 kV TEM. The utility of replication was recognized immediately and many variations on the theme, including two-step negative-positive replicas, soon appeared. Intense development of replica techniques slowed after 1955 but important advances still occur. The availability of 100 kV instruments, advent of thin film methods for metals and ceramics and microtoming of thin sections for biological specimens largely eliminated any need to resort to replicas.
