Thank you for your work at REPEC and CollEc. In recently exploring CollEc, I noticed that a lot of my co-authors do not appear in my official list, even some who are registered and with large networks.

Holy cow! That's sounds very serious.

For example, consider this paper: http://logec.repec.org/scripts/paperstat.pf?h=repec:wly:jpamgt:v:29:y:2010:i...

The paper is in REPEC and in my profile, my coauthors Oates and Sanchirico are registered in REPEC, yet they do not appear in my co-author list.

Upon investigation, this paper appear to be neither in Oates profile http://ideas.repec.org/e/poa3.html nor in Sarchirico's profile http://ideas.repec.org/e/psa58.html

Is this a bug?

I don't have evidence yet. For any paper that would establish a link, your co-authors have to have claimed it. This was part of the reasons for doing CollEc: get authors to ask their co-authors to register and maintain their profiles.

Is there some way to fix it?

Yes, contact your co-authors to ask them to add the paper to their profiles. Note that CollEc updates slowly because of the huge amount of calculations required; but if you get a new connection you should see your ranking increase over the space of about a month. Yes, it takes that long. Cheers, Thomas Krichel http://openlib.org/home/krichel skype:thomaskrichel
