The only requirement is to make an Internet Archive account. (If you already have an account, check if it was compromised in the recent hack and change your password.) Note that this is in no way a comprehensive list of works or an ideal Tintinology primer, just the books that have been made available on the archive, which also means that it contains everything from picture books to highly academic texts. However, I've marked with a * the books I think are best to start with.
Includes works in both English and French (plus a few in Spanish). Please don't hesitate to ask if you have questions!
