Did you know that September 20th was Software Freedom Day? Are you hosting an event at your library? I wrote about the event here: http://blogs.liblime.com/open-sesame/archives/129 and you can read the official page here: http://softwarefreedomday.org/
It's not a day I've heard about before, but it sounds like a great way to get the word out about OSS in our libraries - I just wish I had read about it sooner.
