I completely understand wanting to use a service that has the books you're looking for and would also completely understand if it's too much work to type up the examples. If you'd rather not do so publicly, happy to receive your email at <mek@archive.org> and do what I can to help. Thank you!
Here it already only has the printed version, not the main kindle version (his books are KDP, so sadly Amazon-exclusive). It’s also lacking the Series title (Scattered Stars: Evasion), only having the book title "Evasion".
Missing from the series are Discretion (Scattered Stars: Evasion Book 2) [1] and the new Absolution (Scattered Stars: Evasion Book 3) [2].
Looking through his other works, they all seem to only have the print version.
I’m also not sure if the ImportBot [3] is official, or just one huge contributor, but it could really do with some kind of information, including how something like this could be fixed, or if it can.

After GR removed the ability to add books manually by users and added stringent rules for them to be added to consideration by "librarians", I stopped using GR.
I read a lot of obscure books that often don't have ISBN or an webpage (!). I can't track them or add them! It was so unfair.
So, I moved to OpenLibrary and have been using it ever since.
I read some books cover to cover, and some are kept as references. Books are mainly on Math, Philosophy, and History. There are other topics, too.
I read in 4 languages and GR is very Anglo-centric. That's another issue.
I wanted to track my to-read and read for every book that I found.
I cannot do that with GR anymore.
(I am unsure to whether you are asking about my use case about the sites or the books. So I answered both.)
