Heal Central is the International Association of Medical Science Educators (IAMSE) digital library and is another useful digital repository that allows medical educators to discover, download, and re-use over 22,000 medical education resources. The IAMSE and the co-directors of the Health Education Assets Library (HEAL) have been working together to further the development of HEAL to become a dynamic, user-centered digital environment to allow medical educators to share and discuss teaching resources and methods. This is being accomplished through the incorporation of key characteristics of Web 2.0 technologies, including user reviews of resources and user tagging (searchable keywords) of resources.
