Library Resources
Does a Library count as Open?
The short answer is, no. Library resources are collections of copyrighted materials. However, these collections hold diverse selections of quality academic resources that have already been purchase on your and your students' behalf. These can be used in incorporating accessible and free materials into your courses.
Library eBooks can be used as textbooks, primary or supplementary. Links to articles in library databases make great, current information points to share with your students. Films in library databases provide both inside and outside the classroom educational experiences for your students.
