My end-caps were extremely vanilla, with just the Dewey numbers. After attending a webinar on how to use PowerPoint to make signs, etc., I did a quick and easy sign with the subjects students will find on each shelf. Works better than a Wordle, because I could control where the words appeared. (The sign is straight on the endcap, just crooked in my photo!)
Thanks to Kathie Maier for the idea!
