The teacher-librarian should be the most effective weapon for collaborative teaching and learning within a school. Teacher-librarians do struggle to find time to effectively plan for the cooperative teaching and learning activities. Often school libraries run their own website as they struggle to offer a digital 24/7 library service for its users. The school library website makes it easier for the teacher-librarian to manage the information delivery but isolates the content. The teacher-librarian managed website is often not an effective tool for cooperative planning and teaching. This paper will look at how the teacher-librarian can use e-learning platforms to deliver a digital 4/7 library service, and in addition, offer a great collaborative space for effective cooperative planning and teaching. This paper will focus on examples of practice in two schools. The first school is a New South Wales government high school and uses Moodle as the e-learning platform. The second school is an international K-12 private school and uses StudyWiz as the e-learning platform. (Contains 5 figures.)
