2014 is the 60th anniversary of the St. Louis Browns' move to Baltimore to become the Orioles.
Similar to the Cubs' 100th anniversary of Wrigley Field celebrations this year, the Orioles are planning many events to mark their own mileston.
One of those is a cool thing for any baseball writer or researcher, but even if you're just a casual fan of the sport, go have a look at this page on the Orioles website, which contains every media guide the Orioles have published, through the 2013 season.
The cover images alone are worth the visit to the site, and you can read the pages online or download them for offline reading. Looking at the changes in ticket prices is a fascinating trip through baseball history and there's a ton of other information that's useful for anyone researching baseball history.
Now, you might be wondering why I wrote about this -- we're not Orioles fans here. Beyond the fact that this is really awesome for any team to do, I hope the Cubs (and, really, every other team) will do the same thing. I have a collection of Cubs media guides going back to the early 1970s, but I'd love to be able to access the rest of them, going back as far as the team can, to have this kind of historical information available to anyone.
Go for it, Cubs.
