I made a bulletin board display (it's hard to read in this picture) that shows all the books written/published in 2000, the same year Rolling Hills was built. Believe it or not, this was a REALLY hard thing to do! I had to Google image search and then cross check on Destiny or a website on the publication date. Some titles include Because of Winn Dixie, When Sophie Gets Angry, Olivia, Year Down Yonder, Franklin Forgets, Bud Not Buddy, Harry Potter & the Goblet of Fire, Stargirl and lots more!
Finally, my second graders wrote and illustrated books they like to celebrate/books they like. I used those pennants to line the front doors of the library.
In addition, we have a big 15 year celebration assembly planned for May 15th at 2:30 as part of our school's Step Up initiative.
