I love going to used bookstores. Surprisingly, I have never come across either of my own books at any used bookstores. I took that as great news - everyone wants to keep my books!
I was able to find a copy of World Cup of Hockey in Russell Books in Victoria when I was on vacation this summer. It was a nice surprise:
If you are ever in Victoria be sure to check out both Russell Books on Fort Street and Snowden's on Johnson Street. Also head out to Sidney for 12 other bookstores in all within walking distance of each other. Just go early. Most close early.
