I hope this is not *too* off-topic, since it isn't about Gutenberg but it is hopefully a topic of interest...

I want to see a book at Google Books, The Secret Tomb (https://books.google.com/books/about/The_Secret_Tomb.html?id=0NMCTgniOIsC.

This book is published in 1923 as can be seen from the first pages, so it became public domain this month.  Google Books has a "Report an Issue" link which includes an option "I¢d like to see the entire book, and I believe the book is in the public domain".

I reported it and got a form letter reply from someone who obviously didn't understand my request and claimed that according to the publisher, the book was produced in 2009 (maybe, but it was obviously just a scan of a book from 1923, with a generic cover tacked on by a "publisher").

The book doesn't seem to be available on archive.org or on Project Gutenberg.

Has anyone here had experience trying to escalate a request for a public domain book from Google Books?
