ISFDB, the Internet Speculative Fiction Database, is used in a lot of answers on this stack. It was notorious for not facilitating https. That has now been fixed, if I interpret this related FAQ correctly.
Ideally, we would now like all links to the ISFDB to use https instead of http as well. But there are a lot of links. A lot of links.
Could this be handled by updating the db directly, as has been done in the past for similar situations?
