I did it! I was able to take all of the library’s notifications and put them into twitter.
I set up our twitter account at http://twitter.com/cglibrary
Then I dumped all of the library’s rss feeds into http://www.rss2twitter.com
Now everytime the library has an update, a library event, a new book or video, or new newsletter, it goes automatically to twitter. If the content is too long for the message, it automatically creates a tiny url.
