Don't forget books!
Our art collection is one of the library's greatest strengths--use it! Art books are located in the 700s along the low shelves above the steps. It can still be a bit overwhelming, so here are some of the subsections:
700-709 General art reference
710-729 Landscape, design, and architecture
730-739 Sculpture, pottery, and metalwork
740-749 Drawing and decorative arts
790-792 Performing arts and theater

Finding Art Online
Due to copyright and licensing issues, as well as the fact that art is often scattered in museums across the globe, it can be difficult to find comprehensive sets of an artist's work without paying for it. That said Google Images and Wikipedia are both wonderful resources to find reference images of all kinds of artwork. Starting on the page of a specific country or style or museum could get you off to a good start, and exploring the linked articles within those pages will help you narrow down what you'd like to study.
Gale Virtual Reference Library
Once you've picked an artist, search for them in the Gale Virtual Reference Library, where you'll find hundreds of digital reference titles on everything from art to world history.
The Louvre Collections
Victoria and Albert Museum
