I wanted to pointed out this great web site: Artsy. It is a great source to do research, to find artists, projects or simply good quality images of your favourite art work.
They are featuring the world’s leading galleries, museum collections, foundations, artist estates, art fairs, and benefit auctions, all in one place. The database have more than 230,000 images of art, architecture, and design by 25,000 artists spans historical, modern, and contemporary works, and includes the largest online database of contemporary art. They have all the arguments to be known widely, not to mention that the web site is very well designed.
You can set up an account to create customizable collections of works from the Artsy database, available from the app on iphone as well.
I already pointed out this platform on my article on JR.
