Making a convincing case to change from non- or lightly-managed web sites to a content management system (CMS) can seem daunting. However, you can build a strong case that will help convince administration of the benefits of CMSs. In this talk, two librarians who manage large public and internal websites at the University of Michigan and the University of Colorado Denver give you all of the ammo you need! Gain insight on why having a CMS is better than not having one and why an open source CMS tool (such as Drupal and MediaWiki) are viable, functional, and efficient solutions. Audience participation in the form of group therapy will be encouraged! Concurrent session delivered at Internet Librarian 2011, October 19, 2011, with Nina McHale.
