Hi,
Actually, it doesn't work like that in my data.
I have :
- "ol_dump_2010-11-30.txt" (http://openlibrary.org/data)
My book is related to a work and they both have the same author key.
But the author key doesn't correspond to any author.
You can see as a research in the full bulk file the following results :
"*Search "OL414281A" (2 hits in 1 files)
ol_dump_2010-11-30.txt (2 hits)

As you can see there is the relation between book and work but absolutely
none between book and author and/or between work and author.
Am I missing something ?
Kind regards.
Michaël.
