Hi - I'd like to become a TES author and I'm a little confused about copyright law. As an English teacher I obviously use non-fiction and fiction texts which are current or extremely old. PPT slides and worksheets would need extracts from these texts (and in the case of poetry, the text in its entirety). I've had a look at the guidance on copyright in the Author's Academy section but it seems unclear as regards English teaching. Please can anyone help?
