Good sites for searching colleges and professors

Hi guys,

I am a student who is planning to apply grad school in US, I was wondering what sites are you guys using when you looking for colleges and professors. It’s frustrating for me to search colleges one by one in google.

So far, I only know two sites:

http://facultysearcher.com, a webiste which contains the faculites information of top 100 universities in US.

http://academic.research.microsoft.com/, a website based on the data from academic papers.

Do you guys know other useful sites for searching colleges and faculties? If you have, pls share with us
