This is interesting. For me it seems like me not reaching out for books is a consequence of lazy "rotation", i.e., these are the same books I'd eventually find time to read if I could see them around often enough, so when I have some leisure I don't forget about them. Anyway this is our (my wife and mine) hypothesis - so we are currently working on rotating books, let's see how that works out : - )
