Between 1998 and 2003 the CFT published a newsletter called Teaching Forum which printed articles about a variety of teaching topics as well as notices of CFT news and events. Back issues of Teaching Forum are available online at the link above and in the library.
The Professional and Organizational Development (POD) Network is the professional organization to which teaching centers such as the CFT belong. POD publishes several "Essays on Teaching Excellence" each semester, and these are available at the link above. Note that you must have a VUNet ID and password to view these articles.
