Finding a contemporary artist in print resources can be difficult simply because print publishing requires a longer process and more vetting than the web.
Sometimes, the only way to find print resources about a contemporary artist you are researching is by going on the web to locate additional resources. There are a few places you can visit to find these additional resources.
Artist's Website
Sometimes, artists include a "publications" or "press" section on their personal websites. This can lead you to both articles and books that discuss the artist's works.
Art News Websites
ARTnews.com is a great website for locating articles, publications, and reviews about contemporary artists.
Artsy.net is a great website for artist bios, images, artist statements, and gallery information.
Wikipedia
You don't want to use Wikipedia as a source, but you can use their reference lists as a starting point for locating print publications about an artist. Does the artist you are looking at have a Wikipedia page? Scroll down on the page and find the "References" section to see if any books are listed.
Google - Site Searching
Site searching is a great option when starting a search.
You are able to tailor a search and target specific websites regarding specific artists.
