I've done this bulletin board every year, and the kids (and adults) love it! I send out a letter to the parents asking for random items, and this is what I got this year:) The item to search for changes every day.
This has been CVHS Library's MOST talked about display in a long time! We asked staff and students to take a "selfie" with their home bookshelf in the background and email it to us. We dubbed them "shelfies," a term I hadn't seen before so we're taking credit for coining it! :) We have them displayed on a BB and also in an album on our library FB page. https://www.facebook.com/CVHSLibrary
