Credo is an academic alternative to Wikipedia and is perfect for background research or formulating your topic. It includes topic pages with mind maps (examples: Contemporary Art and Graffiti) and specialized entries from several encyclopedias, dictionaries, and other reference sources (example: Banksy, from Gale Biographies: Popular People).
Wikipedia's Contemporary Art page lists art movements of the 1990s, 2000s, and 2010s. This page can be useful for finding keywords, but please don't use it as an actual source! Wikipedia list of Contemporary Artists
Go to the library's periodicals room and browse the selection of recent art titles. Artforum, Sculpture, Aperture, ArtNews, Print Quarterly, Flash Art, more! These items don't circulate (you can't check them out) but you can use the KIC book scanner to make pdfs.
Check these databases for streaming film segments and for art images. Note that for ArtStor, you MUST sign up for your free account from on campus. Thereafter, you can log in from off campus.
