Yes. But the book id in your export is unique to your shelves. Author 39 has 183 works associated with it, but they aren't all by the same author:

So, you can only determine the title of a book based on the id number if it's on your own shelf, from the data in your backup. No one else's books can be rescued from your data, unfortunately. The id numbers are only unique within your data, and point to a different book in somebody else's data. (I'm guessing that's what I didn't make clear.)
*My information about book ids is incorrect. It is explained correctly in posts 54 & 55*

That is not my understanding but.....happy to be proved wrong, the book id is unique to an edition of a book, it has nothing to do with your shelves.
So by changing the number in the URL you can match your CSV file book id with the book edition on GR.

THe wording after the number is irrelevant

Correct. This has nothing to do with the number assigned the author or title.

I'm happy to be proven wrong. But what happens if you do not have a save file to reference?

I would think that it may be some are never rescued if the people who have shelved them cannot rescue them and no other information is found.
I am glad that you explained the way that the book id works, because I haven't understood it these past weeks, and I do not like to pass along incorrect information.

I suspect it is, because yesterday I typed something (forget what) into search, and in addition the book I expected I got an 'unknown' with an ASIN, and the ASIN led me to another edition of the named book. (So I put in the basic data to the unknown book and combined them.)
It'd be great if we could just rescue the 'unkown' result for "yucky monster" with The Yucky Monster but I don't know if that's right - ?
I would not assume that it is. Among other possibilities, it could be another book with a similar title.

I know, he just copied some of my books which he also had when he was doing initial setup of his account. Now he has no idea what that particular book was :)
As an IT professional with 15+ year experience I find it strange and disturbing that there is no any kind of backup database that would hold a copy of GoodReads books prior to the Amazon's decision to cease its support for the data. Even if the data had been requested from Amazon on the fly every time a particular book's page was displayed (which I find doubtful), some cache of the information could still have been created and stored.
Alexander, keeping the data in any form after January 30 would have been a violation of GR's agreement with Amazon. It's not a programming issue; it's a legal one.

Was able to find a similar title (different ISBN) at the publisher's website http://www.pimsleur.com/Learn-Farsi-P... . What do we put as the author for this entry?

Ehhh.... I would put the author as "Pimsleur". I can't really find any other direct author data, so at this point the imprint will have to do.
ETA: Looks like all the books included in that program are listed here under either "Pimsleur" or "Pimsleur Language Programs".



So far we are leaving even the empty unknown books. According to what I last heard, TPTB have stated that the imports may be able to rescue even those empty books.

That's good to know!

User-added editions and details should not have been touched by the process of stripping away Amazon data, no. (On the other hand, ISBN-less user-added works tend to be duplicate editions, which could quite possibly have been merged with Amazon-added counterparts before the Amazon data purge.)
With book ID I meant the number that is specific for each edition, and you can always find in the link. It seems that the Unknown Number titling is based on this ID stuff. So if you've made an export of your books, you should be able to link these id numbers.
I had rescued everything, so I wasn't able to confirm this, but it's how I'd assume it would work.
