QUERY: Josef Albers. Interaction of Color (2013) Yale University Press

Have any of you purchased the Yale University Press I-Pad publication:
Interaction of Color / Josef Albers (2013)
which won the 2013 George Wittenborn Award?

Have you loaded it on a single I-Pad, and how do you make it accessible?  Have you cataloged it? At Columbia University Libraries, we are grappling with how to handle this title, particularly with the long term access and preservation of its unique content in mind.

I would be most pleased if those who have considered acquiring or who have already purchased this title, or others like it (tablet only accessible titles, or titles that are basically apps) would share their thoughts and experiences.

Thanks so much,
Paula Gabbard
