Before the Internet made the notion of interconnected global communities a commomplace, mail art, artist book publishers and experimental artists forged international aesthetic connections with their work. One magazine in particular grew out of the need to chronicle, reflect on and assist these and other then-marginalized art-forms, and that magazine was Umbrella, spearheaded by Judith Hoffberg. The magazine’s 1978-1998 period of Fluxus, video art and Happenings is here recalled with reflections by and interviews with dozens of the people involved.
