OpenStax CNX: Localization and OER "In the context of OER, localization refers to the process of taking educational resources developed for one context and adapting them for other contexts. These contexts can, for example, be geographical, pedagogical, political, or technical. The practice of localization encompasses more than the translation of materials into a local language or swapping a photo to reflect a culture. Localization is at the heart of the OER process—it exemplifies diversity, openness, and reusability."
If the OER was originally composed by an Open Author in OER Commons, and has been given use licenses that allow for editing and remixing, you may use the "remix this resource" option to copy and edit the resource.
