Try a combination of web searching and library resources to find information on living artists:
For artists from the 20th century and earlier, try consulting a library encyclopedia at the start of your research. Encyclopedias summarize what is known about an artist and their work in a few pages and typically include a list of recommended readings. Encyclopedias are created through collaboration among many researchers. An experienced editor oversees the project and recruits other scholars to contribute entries in their areas of specialization.
Like other printed reference books, encyclopedias often feature high quality scholarship. However, because they are so labor intensive, they quickly become outdated.
Try a combination of physical and online searching to find images of an artist's work.
