Problems adding books


Trying to add this book to Paperpile, but it isn’t working via the Chrome plugin. I was able to add it by searching for the ISBN, but I feel that both of the links below should have worked: (this said that it saw a “paper” in the page, but then added it as a website reference instead of a properly formatted book, as usual) (here the plugin doesn’t even see a “paper” in the page, despite a DOI and an ISBN in the page contents).

Shouldn’t it be possible to grab stuff for any page with an ISBN? I saw another thread about adding via ISBN but that was about adding things manually. Shouldn’t it be possible for Paperpile to “find” the ISBN on any page that has one via the extension?
