These library resources are online, searchable, and provide published sources in the field of art and art history. For most or your more 'traditional' research assignments you'll be doing in Art & Art History, these resources will likely help you find the bulk of the sources you might cite in your papers and presentations- including books, scholarly articles, and magazine articles.
Q: Why can't I access full text for everything when I search through library sources?
A: Good question! We wish more information was readily and easily available to be used and learned from (that's kinda what libraries are about!). Sadly, there are often different copyright and monetary interests that work against this wish. Some library resources are databases, which means that they collect and store searchable resources with the full text right there in the database. Others are indexes and provide citations and information *about* sources on a particular topic to give you a better understanding of what exists and what titles, journals, and authors to look for. Most library resources are a combination. If you find a source in an index and can't access the full text through a Worldcat search or google search for the title, you can request access through interlibrary loan.
