Educators looking for guidance as they expand the role of open educational resources (OERs) in their classrooms can turn to this resource. The comprehensive guide is conveniently divided into several sections and caters to a range of audiences. Those new to OERs will find valuable information on the About page, including a breakdown of the 5 "R's" of OER: retain, reuse, revise, remix, and redistribute. For a reliable list of OER hubs, check out the Quick List page. Educators seeking advice on how to create their own OERs will find step-by-step instructions by browsing the Creating, Licensing, and Collaborating pages. The Advocacy and Sustainability pages provide tips that will be especially useful to librarians, educators, administrators, and other stakeholders hoping to implement OER policies at the macro-level. The guide is available under a Creative Commons License and was originally created by The Learning Portal. The toolkit was developed by Colleges Libraries Ontario (CLO), the Ontario Colleges Library Service (OCLS), and the Institute for the Study of Knowledge Management in Education (ISKME).
