Best Way/Source of Citations

[PundaSmith]

Hello,

I am about to start processing my EB-1B application, and was wondering what the best way of finding citations to one's work is?

I checked google-scholar, and see most of my work referenced and cited there. ISI Web however referenced only few (about 3) of my work.

Which of these sources will USCIS consult or which is preferable? Or should I just combine them?

Thanks - Punda
