I was alerted to some new communications resources from ALA thanks to Peter Scott's Library Blog. The Communications Handbook for Libraries is "a free, online handbook designed to help librarians and others develop and maintain effective relations with the media and win support for libraries and their programs, all with minimal use of precious resources." I have already skimmed through it. It's very thorough and is a great resource for beginners, though it has enough depth to be a helpful refresher for pros as well.
Peter's blog also alerted me to The Smartest Card. The Smartest Campaign, a new toolkit with graphics and sample publicity materials for the new advocacy campaign launched by the American Library Association and Public Library Association. Of course this campaign applies to public libraries.
