IRMA has been updated with additional articles about various subjects. There are a few minor enhancements: we rearranged the tabs on the "Browse" page to indicate what the articles are actually about. For instance, under "Diesel Locomotives" the tabs list the titles: "Early Diesel Engines", "Streamliners", and so on. And under Links, the links now have titles indicating what you're linking to, rather than just the URL
There's one known issue: under the "Visit" category we added a campus map, courtesy of Pete Schmidt. But you can't zoom it up, so it's not very useful. We have this figured out, though, and it'll be fixed in the next release.
Meanwhile we're hoping to have signs put up soon at the Museum to tell visitors about this new app. Enjoy!
