The document discusses opening up language corpora and resources with open educational resources (OER) for English language teaching. It presents the FLAX collections which combine the British National Corpus, British Academic Written English, Wikimedia, and Google N-grams. It also discusses the SPINDLE podcast corpora containing audio, video and transcripts. These resources provide more language samples than textbooks and dictionaries. The resources are aimed at learners and teachers for independent study and crowd-sourcing new collections. They also link formal and informal learning and have potential new audiences like conferences and organizations.
