While we do have some retired video lessons (uploaded to a private YouTube playlist) on how to use HeinOnline effectively, HeinOnline access is not included with any of our subscriptions.
You may find out more about HeinOnline subscription options on their website. You should also check with your school's librarian to see if your school has a HeinOnline subscription.
If you have any questions, just send a message over to firstname.lastname@example.org. We're always happy to help. 😃
