Some of that ends up in the Maps, Media and Timelines Thread. You can put any posts with all that information in there if you have some. In some cases, there ends up separate threads for Maps, Media links, and timelines. Also, you can always pitch to a mod that you think it is time for this case to get it's own separate thread for media links.
Trying to cut down confusion is always a good idea. I will say, however, that it doesn't always stop the questions, because some people don't know where to look, sometimes a search for something doesn't turn it up, and sometimes people just don't look. But at least in the only maps, media and/or timelines, it's a smaller area to search for a link.
