Several Peel District School Board students, parents and community members are concerned about a seemingly inconsistent approach to a new book weeding process intended to ensure school library books are inclusive, but that appears to have led some schools to remove thousands of books published in 2008 or earlier.
In this context, “older” refers to the age of the physical book, not the date it was first published.
No, in this context it is not the physical age of the books themselves as the whole thing is about promoting being inclusive by assuming any book older than 15 years is less inclusive.
The subtitle of the article is “Books published in 2008 or earlier removed from school library amid confusion around new equity-based process”.
