We are a Chicago theatre site...obviously, from our name. However, in the interest of serving our community (which does, of course, travel), we will, as it becomes possible, publish reviews of shows in other parts of the country. Our primary position is that we would like to be the ones reviewing those shows, but we can't be everywhere. Heck, we can't be everywhere even in Chicago. So, yes, we'll link to coverage of certain shows from other sites and/or newspapers, etc. 
We will place "COS Review" in front of any link that features one of our reviewers who happened to travel to see the show in question, so you'll be able to tell right away. Otherwise, we'll clearly credit whoever did the reviewing. 
Just part of our ongoing service, folks. If there is a city you'd like us to cover, let us know
