Johns textbooks, free textbook download, https://drjohncampbell.co.uk/ Just a bit of an update from John. After my experiment with Substack many people have pledged to a paid subscription. https://substack.com/@johninengland?utm_source=user-menu However, I have decided NOT to accept these payments and my Substack will remain free access. This means the pledged money will not be deducted from people’s accounts. I still plan to continue some posts to Substack as time allows. The other factor is that I can still post whole videos directly to Substack. However, for those who would like to contribute to my campbell teaching work, I have created a buy me a coffee account. This money will help in the production of educational materials and support health and development projects in Africa and Asia. Buy me a coffee ink: https://www.buymeacoffee.com/c3kURKNdND
