Comment: Hi OL Team,
We are trying to use the dump files from your covers so we can have the
same functionality retrieving covers for books.
We have found some discrepancies in the covers and I was hoping you could
help me sort this out.
The index files for the covers directories (i.e covers_0003_00.index)
contains the image cover ID number (i.e 003000001.jpg) and the internal
cover ID (i.e 20487)
The problem is that when we are matching internal coverID with the index
files and the master ol_dump_cover_ids file, the image for the cover we
are getting is not correct.
Is there other way to map this files?

For example: Book with ISBN:9780060007058 has an internal cover ID of
20487 and OL key of OL7274396M. In our mapping this give us this cover:
0003000001.jpg
which is not the correct cover for the book.

Any help would be appreciated.
Thanks,

-Alvaro Sanchez
