Lizzy: Roundabout is a specific "company"/"producer" that puts on shows. There are only two independent companies: Roundabout (obviosuly) and The Lincoln Center which currently is holding the South Pacific revival. As you will notice, Roundabout has only done revivals or different interpertations of revivals, which is usually the policy of the Lincoln Center, but they have mounted plenty of new shows.
All other shows are mounted by "private" producers, in that they are not from a specific company. If you live in the US, more than likely you're closest major city has one. For instance, in Philly we have the Walnut Street Theatre!
Therefore, Roundabout is just the "company" putting on the show, in which the venue is the American Airlines Theatre.
When you write to Mary, disregard the whole Roundabout thing! After your letter, just simply request either a PLAYBILL (which you will have seen many successes on the "Via Venue" forum) or a headshot and she will most likely be able to deliver to your request.
Any other questions let me know! Good luck
