Thankfully, we now have 49th Shelf - a site dedicated to Canadian books and authors, proclaiming "If it's Canadian, it's here."
The website allows you to browse category/topic, and also by author. Of course, if you know what you're looking for you, can do a standard search.
Results will provide you with information about the book or the author, as well as link you to other books by that author. It's pretty straightforward and simple.
Signing up as a member is free, and it allows you to create content on the site - such as making lists, aka "Recommending Reading." As a member, you can also rate and review books. In going through the site, however, I do notice that there aren't a lot of reviews. Perhaps that will change in the future.
One really neat part of the site is the Read Local: The 100 Mile Book Diet map (though for such a proudly Canadian site, I wonder why they chose miles instead of kilometers). Anyhow, it's designed to encourage readers to read local, and to do so they have a dynamic map of Canadian with little book markers representing where books are set or the author is from. So, for Grande Prairie, it lists two - Sue Farrell Holler's Lacy and the African Grand Mothers and Deanna Kent-McDonald's West Wind, North Chatter (a novel set in Grande Prairie). As a member, you can add books to the map - so it would be a great way to get some Peace Country representation out there. I know you know of lots of local authors!
Lastly, the blog on the site offers great topics about Canadian books - non-fiction and fiction - and not usually the staunch literary fiction.
I encourage you to take a few moments out of your day to explore the 49th Shelf, and Canadian books & authors in general!
