Hey if you ever wanted to spend your free time looking at free art e-books here you go. They're in a readable PDF form and you can save them to your Google Books library or download them. Its pretty fuckin' great. I just went through a book on ancient Roman gardens. You can browse the other art books they have as well as their exhibition catalogs (which are amazingly done).
I went to the Getty one time back when I visited LA when I was like, 16. I was enamored with the place. It's good to see that they are coming around and joining the open access movement because art books are expensive. As. Fuck.
Also, if finding free content is your thing and you don't already know about Open Culture then you're welcome.
