The aim of this publication is to present how Open Educational Resources (OERs) are being strongly promoted at all levels of education. This book presents a select number of case studies from contributors to the Irish National Digital Learning Resources (NDLR) service.The NDLR service was launched as a pilot project in 2005 and in the last 7 years has grown significantly. Its mission is to “promote and support Higher Education sector staff in the collaboration, development and sharing of learning resources and associated teaching practices for the advancement of academic scholarship in Ireland”. The NDLR is a unique inter-institutional community, fostering the sharing and exchange of teaching and learning experiences, practices and resources, and collaborative research and development initiatives across the Irish Higher Education sector. The service promotes and supports the sharing and creation of OERs amongst the academic community in Ireland.The NDLR, through the local Institutional representative, provides support and encourages the development and sharing of reusable teaching and learning resources to members of academia through the coordination of a number of local initiatives and local supports across 21 Irish Higher Education Institutes.
