To play Ex Libris, first, each player picks one of the 12 unique librarians. The goal is to alphabetize your books to get the highest score. In each turn, use the rotating action spaces to perform different actions. Make sure to keep track of the time as the game lasts about 45 minutes. There are no complex rules, so it's easy for players aged 10 and above to understand. When you're done playing, store the game in a dry place to keep it in good condition. Have fun!
