Inspired by Harvard's Innovation Lab, I created an Awesomebox for the Head-Royce Library. 
OK, so it's not particularly gorgeous or fancy, but it's a prototype.
The idea is that if someone loves their book, instead of dropping it in the book drop they put it in the Awesomebox. Then, I post on social media that it's been Awesomeboxed:
And add a tag in our catalog, so when you search Awesomebox all books marked as such show up.
We've had a few high schoolers/middle schoolers who drop their books in with great aplomb, but generally people are pretty apathetic to it. It's my philosophy that if something can be fun and show that we're interested in what people have to say about our materials and library, it's worth it even if it's not an instant hit. So it stays!
