Yes, there are two book fairs coming up in Ottawa, if you can believe it:
Prose in the Park: June 6: the first of what suggests as an annual event, comparable to when we used to have Word on the Street in town (remember those?). Big, medium and small publishers will be displaying and selling their wares, and a number of authors will be reading throughout the day. And of course, Chaudiere Books will be there as well (thanks to Marilyn Irwin...).
the ottawa small press book fair: June 12 (pre-fair reading) and June 13 (fair itself): co-invented by myself, I've been running it twice a year since it was founded way, way, way back in 1994. Quite honestly, the best of the small press. If you love great writing, small publishing and a whole ton of local materials that you might not otherwise be aware of, this is your event.
And then, of course, Congress is happening right now at the University of Ottawa, which also includes a book fair.
We live in glorious times, I'd say.
