The personal library of Professor Richard A. MACKSEY of Johns Hopkins University, Baltimore, Maryland. It contains over 70,000 books and manuscripts, as well as other art (worth over 4 million USD!) - which he is leaving to Hopkins' Sheridan Libraries in a bequest. Sounds like a great teacher and human being! Check out the tribute vid at the link.
This is what we're planning to do in the A-frame loft. It's already painted; we just need to install the book shelves and start collecting books! Thanks for sharing @Kim Bartling! (And be sure to come out and use our book nook when it's finished...)
