Problem

There's an inconsistency between the availability displayed on Borrow buttons on reading log carousels and what is available when you view the reading log shelf.

I saw this a week ago and ignored it thinking it was an availability caching issue, but the problem has been consistent.

Notice that all the books on this shelf carousel have a Locate button, indicating that they're not available in the library:

However, if you view the reading log shelf, they are all available (one is even public domain):

The common denominator with all the books showing Locate buttons is that their reading log entries refer to specific (available) editions, not just the generic work, so presumably the button logic on the carousel isn't handling that case correctly.

Reproducing the bug

You could probably add these particular editions to a reading log to get the same result.
