Google Books is long dead. If you click on the author's name in one of the results, it will search inauthor:"Author's Name" and this search will return garbage because it chokes on double quotes. This has been true for at least a couple of years; Google Books is not compatible with itself. Changing the double quotes to single quotes fixes it. Also, lately, when you filter only for books that have Full View some results that have Full View get dropped for no intelligible reason.

Nobody is looking at it. I wouldn't be surprised if the preview search was switched off by accident.

For me Books is only useful (and it is very useful) for books out of copyright, 100+ years old. Sometimes they aren't at archive.org.

I hate Google, but I think it's a bit absurd to criticize them on this if somehow it's over AI. The only reason Google created Books may even have been AI, but they were hoping to have the books open to everyone, and the publishers and authors whose full text is being blocked are literally the people who stopped it from happening. Maybe they spoke up about AI, too. I find it even hard to even criticize that Google doesn't take care of Books - it has no purpose or profit potential for them anymore, it's obviously charity that they don't take it down completely.
