You're looking for an archive for https://dictionaryofarthistorians.org while it has just changed its domain: it is to be replaced by http://arthistorians.info/ (and suppress .htm at the end).
Please consider this example: https://en.wikipedia.org/w/index.php?title=Alois_Riegl&diff=864039813&oldid=863837263

As I'm not used to edit here, I just wanted to make sure the context was clear for you: I was redirected here from https://en.wikipedia.org/wiki/User_talk:InternetArchiveBot
Can't you just replace the url instead of searching for an archive? There is no redirection, alright, but the content is the same under the same ID (page name : "riegla" in the example above), only the website changed, and there is no .htm extension. It's a pitty to have an archive while we can have the true website, isn't it?
