I was looking at the Assemblathon2  paper in Google Scholar, lamenting the fact that it is still not properly indexed when I got to noticing something funny- the number of citations the paper has received varies depending on whose page you are looking at. 3 different pages, 3 different numbers of cites.. I wonder which is right… See the screenshots!

My page says its been cited 11 times:

Shaun Jackman: only 6 times

Keith’s page says its been cited 13 times..

Anybody can explain this behavior??
