I retired in June 2019 after 35 years as a teacher, including 31 as a teacher-librarian. I've taught at all grade levels except senior high school, both in the classroom and as a teacher-librarian, partnering with classroom teachers. Canadian teacher-librarians are subject specialists - our subject is information: helping students determine what is needed, how to find it, how to evaluate it (a MUST in the Disinformation Age), how to shape it and how to present it to one's audience, which is why the vast majority of my resources are geared to curriculum topics, rather than the library/learning commons. I have always said, when asked what I taught, "I had the best job in the school!"
