The greatest (and by that I mean largest) of all the Christmas Book Trees, at the University of San Francisco’s Gleeson Library. It is assembled almost entirely with the green-spined National Union Catalog, a bound book catalog that is a relic of librarianship past.
Their 2012 version took 1,500 books, weighs a staggering 4,000 pounds, and is over nine feet tall. It stands beside USF’s Cable Car Book Cart.
