e-flux journal

e-flux is an artist project that emails tons of press releases, exhibitions, and events to interested parties. If you don't mind flooding your inbox their emails provide information on international artists, museums, institutes, curators, journals...most of this information can be found on their website.
e-flux also runs an exhibition space and office space in NYC where they house a collection of artist videos.
They edit an online journal as well. This issue focuses on education:
