The links to Ars Subtilior's site all go to a parked domain page, and I couldn't retrieve the two editions I wanted from the Internet Archive. Should these be marked as permanently unavailable? Kkroon (talk) 20:26, 20 September 2020 (UTC)
Thank you for spotting this. We will have to write to the editor regarding the issue. Claude (talk) 07:30, 22 September 2020 (UTC)
