What a great find! Check out the Getty Museum as it has put more than 250 art books online for anyone to read online and or download. You can find all of these books in the Getty Publications Virtual Library. I love that you can search through the collection by author, keyword, or title. You can find all of the free books on Google Books.
Applications for Education
The Getty Publications Virtual Library could be a great resource for art teachers and their students. Students who are researching artists and or art movements could consult the collection to find reference materials.
I also love the fact that you can embed the books on a blog or website for easy access.
This is definitely something you want to bookmark in your favorites.
Also check out Metropolitan Museum of Art's collection of nearly 400 free art history books. This links also provides access to over 25,000 free images of art you can re-use.
