TIL about Canada’s answer to bookshop.org: ShopLocal. Given an ISBN, it pops up a map to local indie bookstores with that book. Example:
I’m going through my blog and adding ShopLocal links to all the relevant posts. To use it yourself, add the book’s ISBN to the end of this URL: https://shoplocal.bookmanager.com/isbn/
Or use the ShopLocal URL generator I created here: https://nrmroshak.com/shoplocal-book-finder/
