Intermittent results

[TaylorHuston]

For some books it works perfectly. but for others it doesn't seem to be able to find at all, even when searching by the ISBN (and confirming that book exists in Google Books).

For example, I cannot get the plugin to find this book: https://www.google.com/books/edition/Democracy_Or_Else/4cIa0AEACAAJ?hl=en

I've searched by title, ISBN, and author.

I've tried reinstalling the plugin. I've tried other books, and some work, some don't.
