backward CK relationship link

Hi! I am puzzled in backward relationships for Paul Erdős.

The link http://www.librarything.com/commonknowledge/search.php?q=Erdos might not indicate them all because there are many spelling variants for the author.

It could be a suggestion for a new feature.

I wonder if there is a workaround available today.

Thanks in advance for any hints. Reinhardt

FYI: http://en.wikipedia.org/w/index.php?curid=9742 Erdős number

Oh, dear. "Co-author" is not a "relationship" for CK purposes. That field is basically for relatives, by blood or marriage (or the equivalent).

I know ...

It is an impressive work anyhow.
Maybe one should add to the field "Awards and honors" for the "Co-author"s:
Erdős number (1)

This would help to identify them using:
Common Knowledge › Search › Erdős number .
