When I was the teacher-librarian in my school
I had a display for the Author of the Month and I also posted
books for the month's theme.
For example: For March - Women's History Month
I posted every marking quarter's Honor Roll as well as any
other award winners.
I also had a map of world showing countries where
our students and staff came from.
There was a poster of graduates of our school
including a former heavyweight boxing champion.
