Contact North is now also hosting the third edition of Teaching in a Digital Age: https://teachinginadigitalage.ca/
It is also available from BCcampus at: https://pressbooks.bccampus.ca/teachinginadigitalagev3m/
At the moment, BCcampus’ Open Textbook site is listing only the second edition, but I am assured that this will be updated to the third edition shortly. All the translations for the earlier editions are currently available from the same BCcampus Open Textbook site.
There are already volunteers working on updates to several of the translations for the third edition, although I am still looking for volunteers for the French version of the third edition.
