Holiday Book Tree At The Keele University Library
BOOK TREE.

Library and literary miscellany from your pals at Library Journal.
(Maintained by Molly McArdle, Assistant Editor, LJ Reviews)
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.
