Get those books moving in February!
Robert Shuck, Librarian at Harvest Christian Academy in Guam, wrote recently on LM-Net about a great February promotion: "It is called Blind Date With a Book. You wrap the book with plain paper. Draw and design and put catchy words. You only expose the Barcode of the book so you can check it out."
I googled around and found a number of libraries planning on doing something similar. (See the "Infowhelm" blog link above.) Paired with a flashy poster and some heart stickers, this could be a lot of fun. Get students to wrap and "label" their favourite books in the lead up to Feb 14th. You could also tie it in to "love your library day".
